There are 12 questions in the unanswered list.
That's insanely low for a site of our size. One of our closest comps as far as site size and traffic is the Christianity site. There are nearly 50 unanswered questions there (still quite low). Another solid comp UX has 86. Travel has 26.
Only six have been there for more than a month. Again crazy.
That said, if you want answers to these questions, you've got options.
Research the question yourself. Sometimes all it really takes is someone to do some leg work. If you've got the time and energy and you care, why not do it yourself.
Publicize the question. Twitter is a great place to be a gamer right now. If you follow the creator for a product go ask them on twitter. If you know of other experts, follow up with them. FB and g+ might also be good. We also have a very active chat community on this site, with some true experts hanging out there. If you think a question has been passed over, come talk about it in chat.
Edit the question. Editing always bumps the question to the top of the list. This is like a free, 2 day bounty. Don't do this often, but if there are fixes to be made, you can always suggest an edit and have the question bumped.
Ultimately, these questions are already presented in the unanswered list and that means that they are relatively easy to find compared to other old questions. If people want to find things to answer, they will. If people take advantage of favorite tags, then the list is even more focused.
Addendum: I've looked at all the questions in the unanswered list. I don't feel like any of them really merit a bounty right now. I've got reputation I'm willing to give away, and I've invited folks to suggest posts for me to bounty in chat. Only one person has taken me up on it so far, but stop by and make the case if you've got a pet question.
