Dave Sifry’s back with another State of the Blogosphere and the numbers are, well, see the title. We remain on track for everyone in the world to have a blog by 2009 or so. A mild gripe: Dave says “blogs” but he really means “feeds”, a lot of them aren’t blogs at all. Still, we’re up to 3.9 million of them being updated weekly or better. The media spectrum is getting awfully smooth, whether you’re talking about the output of a multibillion-dollar media empire or news from your brother’s family, they’re all just tabs in the aggregator.
