Follow Google to Spamsville
Spam: The never ending bane of a Blog's existence. The very essence of a quality blog publication, is the interraction, communication, and connections made from the beginning of an entry, through the complete thread of its discussion, and ultimate disposition of greater understanding by all. Spam gets in the way of that process. It's not a new story on the internet, of course as many once interesting discussion forums can attest to.
On Meyerweb, More Spam To Follow discusses the new points raised from Googles implementation of the "Nofollow" tag, which will prevent (allegedly) the Bot from exporting Google "juice" to it's linking destination.
Personally, I have mixed feelings about this. No Blog owner can tell me that they don't appreciate a nice, shiny green P7 bar of popularity and importance. So, what of the interesting posts? What of the posts that were on target, fluid, and meaningful? Do all legitimate posters feel absolutely no interest in getting some "juice" in exchange for being a part of a noteworthy discussion? Am I completely off base here?
See, I think "spam" is absolutely a pain in the groin, but that doesn't mean that the Google "juice" isn't an integral part of the modern day blogging experience. The "nofollow" tag will not prevent the spammers from coming back again and again. All it will ultimately do, is punish bloggers that are just trying to publish their blogs, and get recognized in the search engine.
On the other hand, spam needs to be dealth with effectively in order for the dialog to continue. I agree with Eric. The easiest way to deal with it, is to use a cognitive process. Deleting posts you dislike, and keeping (and rewarding) posts you like, is ultimately, the only way to resolve the issue, alongside "preventitive" methods, like the methods employed by Jeremy Zawodny.
