Found an article about making money by using Yahoo Answer:

“People are asking questions because they want your Advice.

So what if someone is asking “What’s the best mortgage for me?” then
you’re pointing them to a Mortgage Company via your referral link? ;)

Yesterday I experimented with what works on Yahoo Answers.

1. Mortgages
2. Personal Loans
3. Credit Cards
4. How To Ebooks
5. Ringtones
”

Note to self:
worth a try
