I think I would happily pay for a subscription to #Twitter if Twitter:
* had no #ads
* showed a strictly chronological timeline of what you're following (and only that)
* offered #RSS (of accounts, hashtags)
* let us edit past tweets
* …while always preserving a history of changes and deleted tweets
* were better at flagging NSFW, and let us customise visibility of those tweets
But I'd rather pay the same money for the 
#Fediverse and 
#Mastodon to:
* improve and evolve
* become simpler to use
* promote themselves so that they become way more popular
Make posts as big as you want
I know people always recommend Mastodon and it is a great platform, but from time to time I remind them about the awesome Friendica :)Basic font styling + markdown support Inline media for posts
RSS support (you can follow any RSS source)
Modern interface (we even have a custom theme at social.trom.tf)
Supports Mastodon's API so any Mastodon app works with Friendica
