Google to announce new tag attribute
Birthday boy Robert Scoble is trying very hard not to spill the beans on a new tag attribute scheduled to be announced by Google later today. Dave Winer mentioned something about this on Friday. It's probably this step to fight comment spam. Speaking of which, I installed MT-Blacklist 2.04b at the weekend and so far it's doing a pretty good job.
Update: Google posted details. Basically the search-engine will not rank links that have an additional attribute "rel=nofollow". So, if you have comments open on your blog then the weblog software would automatically add that attribute to links inside the comment area, preventing comment-spammers from raising their ranking through spamming the comment with links.
