I like it.

That's kind of like what WonderResearch does, which works really well for the site creators, but it is not profitable for the researchers and often people complain of having their research turned down due to 'customer is always right' (sometimes people just ask questions with not enough info out there, and they should still have to pay for the service, right?)

You are definitely on to something I agree; this problem with WonderResearch is something else Steem can solve

Wonder works it out so people have a time limit before someone else can claim the bounty so this stops many people doing work for nothing.

Since Steem is public, everyone can see the quality of a user's answer (and in turn the diffficulty of the bounty issue proposed). Then it effects that users known reputation in terms of claiming these bounties; if they are trying to game that system people won't accept them and it is taken care of in a decentralized method.

Cool!
