Why are bounties time bound? Clearly the site doesn't get enough traffic to ensure that in 7 days the appropriate users (who specialize in the domain of the question) would have stopped by Ask Ubuntu and stumbled upon the featured section.
Also, how can I promote my question? I've put a 300 point bounty on it and it's been 4 days and only one person has even SEEN it.
I'm going to walk away from this thinking bounties are a glorified waste of points.
I suggest a new feature that bounties not expire. I don't see the harm. You lost the points anyways, and if someone ever comes along and answers, even past the seven days mark, they get a good reward in return, so everyone's happy.
