I was reading the about Technorati page and I started to wonder: Just how many blogs are there? According to the site, they index 39.7 million sites, but they also cite this Pew Internet study which suggests that there are 50 million blog readers. So, I’m not sure what to make of this. Are we to believe that 78% of all blog readers also have their own blog? That seems a bit high. It could also be that not all sites indexed are blogs. Perhaps they index not only blogs, but the sites to which blogs link. Or perhaps the 39 million includes many long-dead and dormant blogs. Perhaps spam blogs are inflating the numbers.
Most importantly: I wonder how many active blogs there are?
When I first signed up for Technorati, my “rank” was around 1.5 million. This suggests that maybe there are about that many active blogs, since you would expect me to start at the very bottom of the pile.
But it might be possible that I started in the middle of the pile, or higher. If your ranking is based on the rate at which people link you, then perhaps someone with no links in six months (links older than 6 months do not contribute to your link count) would be ranked lower than someone with no links but who was brand new. If this is the case, then 1.5 million is the “starting point”, but it doesn’t tell us how low you can go. Certainly there are blogs out there which have gone unlinked for ages, but how many are there? How many blogs out there are people just talking to themselves?
