I am building a web application in python that prompts the user for a question that they want to have answered, then gives multiple answers by querying various Q&A sites (yahoo! answers, chacha, answerbag, etc). The problem is, I'm having trouble finding a significant number of APIs from these sites, other than the ones I just mentioned. Can anyone recommend any (free) APIs for Q&A sites? Niche ones (programming forums / answer boards, etc) also work. Thanks in advance!
