I've just come from reading this post on removing a time in which a bounty can be added, letting users add a bounty right off the bat, something I do not agree with. Whilst I can see bounties taking over the questions I think the waiting time for a question to be answered should be far less than it currently is. If I had to wait a couple of hours I would be happy but there are times when I am truly stumped by something and I will want an answer within a couple of hours.
I wouldn't agree with allowing bounties right from the start, but perhaps it would be good for us to be able to attach a bounty to a question after three to six hours? When someone asks a particularly complex question at a strange time of the day there will typically be very few answers, so perhaps instead of users editing their questions throughout the day to push them to the top it would be nice to be able to come back after a few hours and give users an incentive by adding a bounty?
Two days is far too long to wait for a reasonable response. Hell, even a general programming forum will get back to a poster quicker than that. In order to get questions answered and move on quickly I'd suggest changing the bounty time from two days to six hours.
