The Blogosphere is: A - Big; B - Full of Spam; or C - An Annoying GeekTerm?

"There has been an increase in the overall noise level in the blogosphere, most notably in the number of spam and fake pings that are sent - what I call 'spings'," notes Sifry. "These spam pings are fake or bogus notifications that a blog has been updated; in some cases, these spings can amount to a denial-of-service attack, and can sometimes account for as much as 60% of the total pings Technorati receives. However, we've built a sophisticated system that mitigates the spings, and helps to keep spam blogs out of our indexes. Beyond that, about 9% of new blogs are spam or machine generated, or are attempts to create link farms or click fraud."
