I hope Google able to differentiate between actual reply content vs signature content.
That's a really good point. It seems Google "knows" that an answer is in a forum. Google even adds the dates of the answers within the SERP listing. What's everyone's opinion? Does Google know a link is in a signature? Is it possible Google discounts signature links the same way it treats sitewide links? If so, does that make profile links better for SEO purposes?
By the way, I actually discourage the use of forums for SEO purposes. Traffic and mindshare building is perhaps a better use for forums, but not for SEO purposes, for building links. See this discussion in link dev [webmasterworld.com] for more info on how to properly approach a forum for building mindshare.
