A bounty-type Q&A note kind would be cool. Say for example, you have a question you really want answered. So much so, that you put up a bounty of sats to the best answer (or best answers).
At some point (time limit? ad-hoc?) you select your favorite answer to which the sats get sent.
Not sure it'd be possible to lock up the sats to ensure someone gets paid though, without knowing the recipient in advance.
