Yeah, I use lists extensively on X and it was one of the two things that I miss(ed) a lot in nostr until now. I love this new gossip list implementation. Thanks Mike!

(The other thing I miss is the UI ability to assemble my lists in parallel tabs in one wide window like tweetdeck) 

 I can't get lists to work on X.  I think maybe because my account can't post? 

 I'm able to use lists in X accounts that are private / non-posting. But the UI for creating lists has become extremely obscure and unintuitive. You maybe have just not found where / how to create them?

In the good old days, tweetdeck made it very easy. Also when "free speech champion" twitter allowed 3rd party clients, tweetbot (by tapbots) also made it easy and so clean to use. As far as I can tell, twitter under elon is hell-bent on making it entirely un-usable. Aside from people knee-jerk disagreeing with his politics, I think the UI devolution of twitter is probably driving a lot of people to nostr. 

 Followed (kind 3) and Muted (kind 10000?) work just like custom lists, except you cannot rename them or delete them. You can add as many custom lists as you want.  You can add new npubs to them.  You can also go to a person page and flip switches to add/remove the person from any of your lists.  And you can mark people as "private" on a list so when published it hides the fact they are on the list by putting them in the encrypted contents.

I will do a short video on it I think. 

 Does that mean I can view the feed of each of my custom lists and not the feed of my main contact list? 

 Yes. I have a 'news' list that only has news sources. None of that is 'followed' and doesn't show up in my following contacts list.
