I just received the Popular Question badge for a question with zero activity. This represents a question that is commonly asked yet nobody seems to know (or at least has contributed) the answer for. I have moved past the issue and am not interested in putting up a bounty. Nevertheless many people are interested in a solution to the problem (as reflected in the number of times it has been viewed.)
In the spirit of the Trilogy sites being a breeding ground for solid answers to interesting questions, what can be done to promote questions of this category? Perhaps some kind of auto-bounty system? What about 50 rep - something small yet enough to kindle some kind of interest in an answer?
