I agree. The Steem blockchain have a lot of possibilities/opportunities.
There are already multiple video games (for example Steem Monsters/Splinterlands, DrugWars, SteemNova, NextColony, SteemGar), forums (for example TokenBB), poll websites (for example dPoll), video/audio sharing websites (for example DTube, DSound), Q&A (Questions and Answers) website (Musing), open-source contributions rewarding project (Utopian), and other things on the Steem blockchain, and these things (including the Steem blockchain itself) are constantly developing.
If anyone is interested, then you can check more info about Steem related projects in general on the following link:
