I'll give you a few platforms that has particular content requirements. So let us begin.

• If you like to stream while playing game you have Dlive(big guys delegated their steem power so they could support dlive community).
• Dtube - decentralized "YouTube" same thing with delegation.
• Steemhunt-write and comment about newest tech and gadgets and get rewarded for it.
• Steem press-io-allows you to plug in from WordPress and earn money (same thing with delegation by whales).
• Stemsteem supports knowledge and education.
• Utopian-io - if you are good with codes or programming, you should most definitely give it a shot.

I probably missed something, but you'll get there. :D
