The only project in this list that i know of is Sola and of course Steem lol, I tried Sola out in the early weeks because someone invited me but i never sticked to it, maybe i should go back and give it a second shot.
For a project you didn't mention, there's ONO which is actually quite popular here on Steem (i think? I see their post about them a lot or maybe i just follow people that share them a lot)
I also tried sola but failed to adjust to it hehehe..
It has failed to pick up though and that diacouraged me...It is a 2014 project but has failed to pick imo.....!!
How was your experience in Sola?
