while we put our link at there, if not mistaken, the link are "no follow", other then attracted traffic, does it help in search engine indexes?
It was my understanding that the links were dofollow. I do know this much, whenever I answer a question, I get three or four direct hits to my sites and it always ends up getting me some adsense clicks at the very least.
