So many social platforms being on worked on at the moment, although few are actually live.

I tried Sola for a while and its ok for posting images, but the quality of content is really not great. Not much originality, and I found myself scrolling for a ages before finding anything decent.

You are right about Ethereum not being right for social media - it's a hard sell to get people paying to post or 'like'. The exception here is Peepeth - which is a decentralized Twitter built on Ethereum - nice UI and u can stack posts so you only pay gas once in a while.

It will be interesting to keep an eye on some of these, especially Mithril, Loom, Snovio (ridiculous name, good concept), Sociall.
