Dave Sifry has posted October's state of the blogosphere, part 1, which largely documents the continued growth in the space. With 70,000 new blogs created each day (that's a new blog each second), the total number of blogs continues to double about once every five months. This report also takes a look at spam blogs, finding that from two to eight percent of newly created blogs are splogs, and about 5.8% (50,000 posts per day) of the total posting volume is accounted for by fake blogs. The recent spate of spam attacks is apparently not the result of any increase in frequency of splog posts, but reflects a change in the splog keyword strategy to include a list of popular search terms which included bloggers' names — which explains why suddenly everyone's ego searches are turning up nothing but spam. Considering the resulting outcry and new focus on getting rid of this crap, let's hope the spammers have perhaps met some of their last keywords, eh?
