Do you use Yahoo Answers to build backlinks

I think Yahoo answers will help raising traffic, like promotion, it helps beside good contents and backlinks of course.

 

I uses Yahoo sometimes but I more use in searching in Google about that.

 

I have not used yahoo answers for getting backlinks yet however I also believe that backlinks from yahoo answers does not have much value in terms of backlink rather yahoo answers can be used to attract little traffic. Just a thought of mine.
