My cohost experience has successfully recreated the ideal shape the tumblr feed/twitter feed took back when i used them the most, which is, roughly:

• CSS buffoonery, formatting funsies

• A lot of tech discussions from tech people

• Jokes from my funny friends

• Discussions about media

• Cool photography from cool people

• Discourse where it's a largely amicable agreement that [thing] is bad but then there's one doofus who should really stop talking but who cares, you can silence their posts

• someone complaining about the discourse without realizing they can in fact silence the posts too, there are simple solutions to life's problems

• A LOT OF REALLY QUEER PORN

• Repeat from Jokes

This is about all I want from my social media, such as Cohost qualifies as social media fused with a blogging site
