Some points from my post:

Bounties could be used to create cash-inflows that will allow growth and value without sending away value of the ecosystem.
Anyone could ask the internet a question, put a bounty on it and the world would compete for the best answer. As such bounties could be a whole new way information exchange on the internet can be rewarded.
...steem can create one more new monetization layer for the internet and become much more valuable than just with one way of monetizing its content.

I would really like to hear what you think.
