Incentivization for good teaching and a rewards system could definitely be done on steemit if a sub community was formed or if someone launched a Smart Media Token for this purpose it would also create a means for a rewards system that operates on the steem blockchain but is its own token.

I don't know all the ins and outs of creating a SMT but there are people who will be launching their own this year and that's part of what is driving speculation that STEEM will appreciate in value quite a bit in the future.

Nice post and discussion about the topic. There's definitely teachers who are just there for the paycheck (which varies greatly depending on where one lives) but there are also some outstanding ones. It would be nice to be able to reward the good ones with a bit of a bonus somehow and using blockchain tech sounds like a good idea.
