Great initiative guys.

I like to suggest some big categories.

1. Entrepreneurship
2. Business lessons and tips 
3. Personality development

You can add me @Men ☕ in personality development, 😁

Soon will do research and suggest some in each category.

Give me some time. 

 Looking forward to your suggestions! Thank you ;) 

 I second this! 🙌🏼

All of them, especially personal development! 🙌🏼✨

You can add me to personal development as well if you would like  @daniella

Maybe also #spirituality (any faith) or #consciousness which are topics that do come up in relation to Bitcoin in the community as well

Thanks ✨ 

 Nice 🙂 

 I still say to follow everyone who you find curious

also @Global Sports Central does great content
#sportstr 

 This is great! Thanks for the suggestions! ;) 

 This is very needed to widen the scope of discussions🏆great work. I do art. Will stay in touch.

 Agree with @Men ☕ 
entrepreneurship should be added as a category 

 🫡 

 How to add someone to the list? 

 Take a look at the old school Yahoo category breakdown. Pre-Google their directory was king and well categorized.

Also as a new #bitcoin nostrich using primal I’d love to be in your list! 

 Art: @Urzeitshop

I post PaleoArt of dinosaurs and other prehistoric creatures by various artists. 

 Perhaps this would be useful to find accounts: https://docs.nostr.wine/api/classification

 A bubble diagram of the data would be so awesome. 

 Good stuff. Privacy & security would be a good category to add. I regularly post high signal in this category. 

 💯 agree. Ava is  very high signal in these areas. 

 I second this suggestion. 

 I think my activism might fit in the categories of #Bitcoin, Human Rights and Travel. 
#SelfShill 

 Will there be any categories for feet?

Asking on behalf of @Derek Ross 

 🤣🤣🤣 Best ever 🤣🤣🤣 

 Sir, I've graduated from #footstr to #thighstr thanks to @Marie 👀

 Bitcoin: @Spirit of Satoshi 

 I intent to develop the XR VR art category . 

I will also try to make integrate some real time 3d view integrated in nostr clients 😉  

 Would really love to be a part of that. VR stuff especially. 

 I’m the bird and Roman history guy. I already called shotgun. 

 @BitcoinDiscGolf for sports, #discgolf 

 #gold or precious metals in general. 

 "human rights" are a subversive antichrist commie thing so maybe nix that - better to call it liberty/sovereignty if you dont want it to turn into tranny-surgery fundraiser. 

 I intend to continue posting on our adventure abord our (@saltylady and I) sailboat around the med. i hope to be posting regular content around sailing, marine life and hiking. Hope this can inspire fellow Nostrers! 

 Gardening / homesteading would be nice.

Any easy way to do this on amethyst? I want to scroll through my follows and select all that fit.  

 What about “shitposting”? I’m a high signal in there /s 🤣

Seriously, FOSS would be a good category 

 Yessss 😀😀😀 

 Category: #Bitcoin (you could also create an #AI category)

Account: @Spirit of Satoshi  

 For gaming:
@Stitch
(he's getting things ready to post again, as he's moving things to nostr) 

 Actually, I'll poke him to be more active, even before the transition isn't done. 

 Make the Wallet button more visible for new users who haven't activated yet. Encourage them to make a first note, set their bio.. 

 For fun, #tardstr is a great hashtag.

 Hey, thanks for recommending us! 

 Not shilling any categories yet, but I'm hoping that down the road, some of those categories (sports, news, art) will have enough content to justify breaking them into subcategories. 

 I hope so too. We're seriously lacking content on Nostr.

 WOW! Thanks for the suggestions! This is awesome ;) 

 Instead of hardcoding starter accounts, we should work toward traversing lists/labels/topics based on WoT (maybe bootstrapped by a static list). 

 There is no WOT yet without starter auto-follows, or categorized suggested follows. 

Primal is rightly incrementally improving by going the latter.

What I’d like to see on @damus is a powerful search on onboarding that asks “what are you must excited about”.  If the person types “knitting”, the dozen knitting profiles are returned with option to follow. 

cc @nielliesmons @rob 

 For sure, you always need to bootstrap. And Coracle currently uses static lists too, it's a fine first step. But it would be amazing to see these bootstrap lists turned into a "explore" tool which opens up the network based on dynamic trust networks. 

 This was my idea behind crowd funded classifications that are published publicly via labels. 

The problem is the classification work you’re asking for is expensive (if you use a 3rd party) or time consuming (to build it yourself) and nobody is willing to pay for it. 

 WoT and a seed user npub (inviter) would be a great start 

 nostr:note1vajejjkjd3zadkv3qxx4dhn4j6n2p4f027f8wrch259enrknhayqz2dk30 

 there should be a similar razor as Occams for engineering solutions

the simplest solution out of a range of options is usually the most effective 

 CONTEXT is one of the essential ingredients for getting WoT to work.

Category-specific follows is one example of that. 

 this is something that invites would help resolve... they could see from their inviters' WoT immediately 

 THIS 

 Here is the user story. Shout out to @The: Daniel⚡️ for inspiring discussion at nostrville on my favorite user story thus far

https://github.com/damus-io/damus/issues/1696 

 Coracle has something very similar to this (pubkeys, relays, groups, rather than topics).

https://coracle.us-southeast-1.linodeobjects.com/invites.mov 

 Love the personalization. Nostr needs more personalization 

 it's a client side thing though, just a matter of an invite link with onboarding flow and and immediate view of that feed while they spin up their identity

need an easy flow for nos2x type tool - it doesn't have a keygenerator in it last i recall using it... alby has a master key seed generation scheme but that's invite only, so, yeah

i think if you want to promote onboarding you need to fork nos2x and add a better visual and put a generator and backup word key thing 

 yes just should add... WoT was the killer feature that made it really hard for me to switch to nostrudel because i needed outbox model, and i miss the almost working NIP-42 as well

make outbox model for coracle and tighten up NIP-42 and i'll be back 

 You keep saying coracle doesn't do outbox, but... it does. What in particular is missing? 

 when i use it with my relay's chat bot, which often doesn't have even a profile published to the relay, i get all kinds of funny things happening with DMs, and the NIP-42 often takes a minute to actually go through

i wrote a chat flow that asks the user to reply with a challenge text and it lets me auth on chat in 10 seconds

i've written a tool that knows how to respond to a NIP-42 challenge auth envelope, and it does it instantly, it usually takes a minute or more, way way longer than i have the patience for to do testing

the lack of NIP-42 support is almost my biggest pet peeve of all existing nostr clients out there

it's SO easy to do it, but none work 

 Is that why my filter.nostr.wine relay keeps getting dropped on Coracle? I keep adding it, but it doesn't seem to work and eventually just disappears from the list. 

 ah yeah i get that one too... very often being dropped, or publishing disabled

it's because the NIP-42 support is not very solid yet

it's better! actually, come to think of it, it seems to work perfectly in nostrudel but nostrudel doesn't respond to my relay's auth challenges 

 i can only speculate that nostr.wine accepts posts signed by paid users by default no matter where they came from, and that they are not already existing in the database 

 @hzrd149 @Mazin  question: nostrudel doesn't support my relay in development when it has auth-required in the limitation field of NIP-11 but it does work with nostr.land and nostr.wine - either of you two have any tips on how i get my relay to cooperate properly there? 

 Not me 🤷‍♂️ 

 what relay are you running nostr.wine on? so i can try and figure out why it makes nostrudel do auth... i'm guessing maybe it's a NIP-11 thing, and i thought i'd implemented it but maybe i haven't i mean, if it's vanilla i suppose the relay info page will show 

 it only gives info about it being 0.3.1 what? no software field filled in in the NIP-11 

 doesn't say it's strfry, is it the rust one? 

 The backend is strfry but we run our own custom proxy socket in front for AUTH and account management (not open source). 

 ah, and here we see more reasons why this hasn't become widely supported

thanks 

 i won't be renewing my nostr.wine subscription or recommending it anymore until i hear you open sourced this sprocket

i can't believe what i'm reading rn 

 I don't understand what I'm reading, TBH. What are they doing and why is it not ideal? 

 you know about the direct message metadata leak problem right?

we are so far away from having this solved while people are keeping necessary NIP-42 implementations under wraps

it's short term thinking about their own gain and zero thought about the bigger picture for the protocol and its future, completely unnecessary, there really isn't that many competitors out there and this kind of short cut to keeping them out is contrary to everything this stuff is supposed to be about 

 NIP-42 shouldn't only be a gate to paid access it should also gate access to DMs and application specific data 

 So, you're saying that the implementations are too narrow in scope? 

 i'm saying that it's an elephant in the room - free speech is fine but a reasonable layer of protection against access to privileged data - we here see a prisoner's dilemma that nobody wants to take the cost (a few days effort) to solve, which is abombinable 

 I think this won't change, until more people use SDKs.  Everyone will just build the absolute minimum they need. The correct model is for them to only implement the minimum they need from the core library. 

 Yeah, Nostrudel seems to work. 

 I left the npub and everything off, this time. Seeing if that works. Just the relay address. 

 Ok, but none of that is the outbox model 

 doesn't change the fact i can't use it for testing 

 Yeah, but I can't fix outbox if I don't know what's wrong with it, you didn't answer my question 

 it isn't contacting my relay even though it's in the relay list - the only entry even

it looks like the relay list in coracle still works by the old relay lists and not NIP-65 in/outbox lists, to me, that's why i said it

it only worked well when i ran an instance and locked it to my relay 

 the NIP-42 worked better in the custom instance situation too, like sometimes as quick as 10 seconds or less to auth 

 Cool, I'll look into both those things 

 yeah i saw you had worked on the relay list page to add the ability to easily add more... maybe to add some buttons so you can set relays as in/outbox? 

 Exactly! 

 So what you’re saying is that you’d like your WoT to help you curate the list of categories.

And you’d like your WoT to curate a list of user accounts for each category.

This is PRECISELY what DCoSL was built to do.

The proof of concept already exists as a desktop app, and @kinjo is doing excellent work rebuilding it as a webapp. Stay tuned!

 Memes: npub19cql0qvn3n8t0mx40hnstlurvkatke7r8wjpfg6zvt2vdd3ttkfq66hgvc

 @nostrmeme 

 Thank you for the suggestion!  

 This would be great to help build a more general audience. I think right now it's a real echo chamber that would put many off. Adding curation options on entry would also help those who don't want a totally unfiltered environment. On my first hour on here I saw some extreme shit that would turn many away. Most people still want some kind of moderation and giving them control over that from the get-go (rather than algorithms) would get more on board.
