I was aware of Google Answers where people can go and post any question they want and get an answer for a fee (from $2.00 to $200.00). Their answers are usually pretty smart, being given by people who are usually specialist or well aware of the field the person is asking a question about. Plus if the answer doesn’t satisfy you, the person who replies doesn’t get paid, so he or she’s better off providing a good answer.
Today I heard that Yahoo! provides something similar, called Yahoo! Answers but the system is currently free. That’s probably the reason why there’s a lot of poor quality posts, and it seems that many people go there just for fun, or to make a mock of other people.
I’ve read a few posts and I don’t think it’s the best place to get an answer to your question if it’s something very important to you. I’m not saying that you cannot find good information, I’ve found a very good anwser about SEO but many people seem to post just for fun or to get more points.
