DO anyone of you use Yahoo Answers as a way to improve your SEO indexing? In the past, it used to be such a interesting way to leave the footprints of your community in the web, but now, it has turned to be an over-used giant and people only use it for referencing purpose. I was amazed here that there are admins (still!) who use Yahoo answers to get the word out there, thinking that it is an effective way to get indexed and to stay high on SEO. What do you think?
