Well, now is a good time to buy STEEM if you want voting power.

Now is the worst time to buy STEEM if you are looking for capital gains.

So many people wanted the SMTs...
and any of them that actually had a real plan moved on to use something else or gave up.

Yes Steemit (steem) is very centralized.
However, because it has been very centralized we got this thing up and off the ground. And that is good. Too many failed projects out there. (there is a f-c-book clone that you and your friends can run... barely anyone runs it)

But, it is also a bad thing when you expected decentralized, censorship proof, posting forum.
