An anonymous reader submits "Will the blogosphere become just as spammy as Usenet? There may be over 10M weblogs out there, most of them seem to be fake spam blogs created to manipulate the search engines. Scott Johnson, CTO at Feedster, complained that "at times we see upwards of 90% of the traffic from Blogspot being spam," and the problem is likely to only get worse. Can blog search engines like Technorati, Feedster, and PubSub filter the signal from the torrent of noise? Or will we have to seek new approaches such as the social filtering used by Del.icio.us or collaborative filtering used by Findory to separate the ham from the spam?"
