Should the commenters of this blog just want to generate backlinks then they should at least have the common sense to write a structured and considered comment. All comment spam does is potentially hurt your SEO attempts and generates worthless backlinks. The realsafest way to be a success is to befriend other bloggers who have blogs of similar theme and hopefully generate genuine targeted traffic by posting a well thought comment. I hope some of those people might even give this some thought before commenting after me, Heres hoping.
