Askville is not what it was a few years ago. You really DID have people with many levels of REAL expertise. Answers were not just a few sentences but several paragraphs of text, with pictures. Someone from Askville should link some of THOSE questions. Over time, however, the site changed and people left in droves. Now, good luck in getting any sort of valuable answer to your question there. It is not the IQ of the people that’s the problem, but the number of people who are there to answer questions. And when the people who ANSWER questions well leave, since many of those same people ASK questions well, the amount of good questions decrease also.
