I've asked a question on SO and set a bounty of 50 rep. on it. Would it be possible to permit me to raise this bounty, if I see that it doesn't get enough attention?
You can now open another bounty on your question -- at a higher value if necessary -- if the first bounty didn't get the results you wanted.
I posted an answer elsewhere; but since it's to this question I'll extend the answer and repost it here.
To answer your question, no you can not change the bounty after offering it. Your options are to :
- Keep modifying your question every day of the bounty with new things you've tried to keep it active
- Allow it to run out; award the bounty and re-ask with new question
Also, I don't think your problem is solely the bounty you offered. You also offered it in a very much niche subject. However, the bounty system could use extension in cases like yours.
- Allow asker increase the bounty after x days if they don't receive any new upvoted answers
- Allow them to extend it for another 7 days for the same reason

I also think that substantial edits to a question during its bounty period should reset the bounty and vote count for another 7 days.
Have you considered that maybe its the question that needs some attention? It has been my experience that a lot of bounty questions don't get good answers (or answers at all) because they are worded poorly or are missing important information.
Sadly it seems the bounty system has become the "brute force" solution to getting answers, when there really needs to be some "re-factoring" instead... but that's another topic for another day where I haven't worked 3 12hr shifts.
I suspect that user's who answer bounty questions may evaluate the difficulty of answering vs. the potential gain. In that circumstance, increasing the bounty may lead to more answers, but I suspect only in the case where the question doesn't already have existing answers. That is, if they've avoided answering the question due to its difficulty, increasing the bounty probably doesn't compensate for the risk associated with investing time into a question with lots of existing answers.
I think that increasing a bounty on a question with 2 or fewer answers or a question with no answers with upvotes may be reasonable, but it's unlikely to have an effect on questions with 3 or more answers, especially if any have upvotes. Given the way bounties work and the lack of attention for older questions, answering a difficult bounty question with many answers or upvoted answers carries more risk (time wasted) than reward.
Update: Given that it would only be of very limited use, I don't think it warrants any development time. If it can be shown that there are significant fraction of bounty questions with 2 or fewer answers or no upvoted answers, then I'd be willing to reconsider.
