Yes but quite doable. Too much to do on the fly on the front end, but the heavy lifting can be done ahead of time on the back end.

I built a front end demo using only two data inputs (follows and mutes) which is how I realized it’s too much for the front end. @ManiMe streamlined the download process into a single click and you can try it out here:

http://grapevine.my

It will output the top 1000 recommended pubkeys minus the ones you already follow as a NIP-51 list which you can upload to a few clients (Coracle, Amethyst, nostrudel maybe?) and browse the feed when you get tired of you follows feed. Great way to discover new high quality follows.

 @cloud fodder and @ManiMe and I are working on replicating the above but calculating scores on the back end using a relay that already has follows and mutes data, so no need to dump all of that onto the browser, much better UX. 

 So I did that and have no clue how to view that list on amethyst. Not your problem, just, trying to see the output.  

 Start out going to listr.lol and see if you have a list with “Grapevine” in the title 

 Yup. "Grapevine recommended"  

 Can any #Amethyst users help a beaver out? How to import a NIP-51 list and browse a feed and whatever else you can do with it?

#askNostr 

 Ah. I see. It's just a filter that you apply, basically. I can't see see the list itself, it is just applied as a filter. That's... Not exactly useful. I don't see anyone new on that feed at all. 
 

 No one new? It should omit the pubkeys you’re already following when it builds the list. Did it not do that? 

 Didn't seem to. Mostly just my own stuff comes up. 😅 

 Yup. It's literally a feed of me. Kinda weird, TBH  

 I see your list — yeah, didn’t populate it at all except for your pubkey. Check out my Grapevine list on listr to see what it is supposed to look like.

When you built the list were you signed in using an extension? Smartphone? 

 I can't figure out how to see lists via a different npub. 

Yes. An extension (nos2x, IIRC) on an android phone with kiwibrowser.  

 We haven’t tested list generation on android — maybe that’s why?

On listr you can browse lists of other npubs. Search by username at the bar on the top. Or go to listr main page Activity Feed and right now I see one or two My Grapevine Recommended lists recently updated — the first two I click on seem to have worked (mostly) correctly (except only 878 items, should be 1000? 🤔) 

 I get an error 504 when I click on your grapevine list. 

I dunno what else to try. 😅  

 On listr? 

See if this works:

 That mostly works. 

I can see the list, just not nyms or avatars, so I don't know who anyone on that list actually is.  

 Here’s what I see (not logged in) https://i.nostr.build/GuHLzgOKpohPWAGh.jpg  

 Everything is populating on that list now. So that's cool.

But that's not the same as mine. It's just my npub and that's it.  

 Trying the grapevine thing again, it stalls. https://image.nostr.build/448c86f69873eca7e2b8f69d0b9ad9b9695e3740f155d8e84dc12014d045967e.jpg 

 Huh. It might have finished.  

 It's working now. 

Using the hammer method worked. 😅 

 Yeah you probably need to at least refresh the page once 🔨 

 I did... But I just had to hit it again. 😅 

 I find listr useful to view the list itself. It’s easy to scroll down and check who you’re following and who you’re not.

At first we just exported the top 1000 and you’d get a mix of current follows and suggested follows, but then we figured we’d omit current follows so you’d get a fresh feed from high quality pubkeys.

Soon you’ll be able to generate multiple lists. With / without current follows; Grapevine page 1, page 2, etc 

 I still can't see the list on listr. It's just... A block?  

 Your “My Grapevine Reccomended Follows” list was published to Nostr from grapevine.my. You can confirm this using listr. I haven’t personally tested on android (yet) but I believe you can make custom feeds in Amethyst, using Nostr user lists? 

 Yes. I just was thinking that I could view the list itself, not the filtered results of the list. Not as useful.  

 Interesting. 

If I could see the output. How do I see lists on amethyst?

 Yes it is complicated. But there are a “finite” set of these data types (Nostr event kinds that interact with other events in ways that may be interesting for WoT) to calculate. 

There doesn’t need to be a standard of “which data types” should be used “in which manner” by clients. Some de facto standards may arise, while other algo inputs will only increase in complexity. Standards are not as important as adaptability. 

For the foreseeable future, developers of WoT recommendation engines will have to keep their ears to the ground to adapt their algo inputs accordingly. But this complication does not need to be developed all at once or overnight. 

Mind you, this is a new perspective for me. It’s much easier to just say “let’s make a standard”, to make development easier. But life IRL does not work this way. Life adapts. So we must learn to adapt as Nostr grows.

Today we do this. Tomorrow we do a bit more. Baby steps.  

 💯 

 The grapevine method is the best response I can think of to the XKCD on standards that we all know and love: https://i.nostr.build/fUEDsBnkQhR9IVc5.jpg
