As for steemit, people no longer consider it decentralized after hostile takeover by TRON foundation and some exchange.
After hostile takeover, community forked Steemit to hive.blog, what's your opinion on that?
Steemit was cool. I liked the idea and did followed them for a while and was using it on regular basis for a while.
I got busy with life and left it though. But the idea is great and I wish there was some mainstream site like it.
But again I think it's difficult to create and manage a truly decentralized social media site.
