I was recently looking at the unanswered questions, and decided to give one of them a bounty (I didn't really think about why I chose that one, frankly the silliest of them all... It just looked easy enough to generate a rapid response and leave the unanswered list). I see other stacks have plenty of bounties going on, while we have plenty of unsolved questions that could benefit from them (some that have many visits are this one and this one).
Should we encourage featured questions, and maybe also create some using what some of us find difficult to resolve to go in this list?
