I decided to spend a few minutes during my lunch break looking at questions with no answers: http://stackoverflow.com/unanswered/tagged/?tab=noanswers
I'm not a particularly brilliant person; most questions on Stack Overflow are out of my league. Questions with zero answers tend to be WAY out of my league, otherwise somebody else would have answered them.
A small part of me has a small shred of hope that perhaps there are some niche questions out there that I might have an answer to, because I do deal with some unique challenges every now and then. It would be tremendously helpful if I could sort the questions with no answers to show questions that have tags I'm interested in at the beginning and questions with tags I'm not interested in at the end.
