Steemit is built upon the block chain of Steem and just like it other apps can benefit from the same business model.

Here are 2 ideas for anyone fishing for them:

Create a Tinder-like app and have people earn money while voting :)

Swipe right to upvote. Get a #date, earn steem and pay the bill with it!

Create a Periscope-like or Twitch-like app and have the people watch your livestreems, upvote and earn steem!

These are just ideas and if anyone decides to go through with them, I won't hold them for anything...well, an upvote to this post maybe :)

Enjoy,
