Steem is just as dead, it's main flow was to witnesses and I felt very little went to content creators. It's interface hasn't changed. It is the same platform as when it started.

Trons integration hasn't seen much change if any. It didn't even support the Tron coin to rise.

I think it will be a long time away before either "blow up" but Hive has already started to grow communities. Look at Leo. It is emerging quite nicely.
