Mastodon has been doing there thing for a while, I don't care for the system personally, but they have definitely been doing their anti-Twitter thing for a while so I respect that. Surprised they haven't teamed up with someone in the crypto world by now.

You need to add https://memo.cash/ to your list and maybe check it out. Out of all the sites I use, I don't use that the most at all, but I do check it at least once a week, and has much potential with it's functions (also just happened to link back to a post of yours over there https://memo.cash/topic/ONO+ and is how I ended up reading this post now).

http://yours.org has been working for a while. If Steemit was like Tumblr, Yours would be like Medium.

Also possibly look at http://lbry.io as if you boot the app you will see it is a pretty social feeling app. It is like a beefed up working YouTube. I love DTube but LBRY is leaps a bounds ahead, and people who use one, should be using both platforms to be sharing their material.

If you haven't checked Golos since it was more or less a like exact Steemit clone, it really has grown a lot functionwise that I bet a lot of Steemians would be jealous of some functions they have going on now http://golos.blog/

Thanks for this post, I need to check out some of these other networks soon.
