Daily Volume is the Blog Stat to Watch

Nearly every week it seems we get a new stat about the size of the blogosphere. BlogPulse is reporting nearly 14 million of them. However, this figure is somewhat misleading since there are lots of abandoned blogs. The key stat to watch is the volume of posts per day. This is a better measure of the size of the blogosphere, in my view. David Sifry at Technorati wrote today that the search engine is seeing more than 900,000 posts per day on average, which means about 10 posts per second. That said, daily volume isn't perfect a perfect metric since spammers are turning their attention to to the blogosphere. Still, it's the best we have right now.
