Accept rate usefulness
I have an accept rate of 52% and people are telling me they do not want to answer my questions because it is too low. So I would be forced to accept some unsuitable answers if I want to continue to use Stack Overflow.
In reality, it is hard to find a correct answer to many programming questions because many questions would require considerable time to investigate, so the natural result would be that many questions would be left unanswered. 50% answer rate is about correct. I suggest to remove the acceptance rate so that users will not be forced to accept some fake answers and turn SO into a PC but useless pile of junk, like yahoo answers. It's all about pros and cons.
