I think STEEM is the most promising.

FB is because too old - so there are many members.

TWITTER would freezes your account casually, so many people leave.

Telegraph has a limit on the number of people and the number of channels, so often use's people will not choose him.

Therefore

I think STEEM should be TOP 1 in the future.

Maybe Kryptonia/Kblog at the future could to be TOP 5
