State of the Blogosphere
David Sifry of Technorati posted his latest State of the Blogosphere, asserting that growth rates in the blogosphere remain vigorous. Umbria has an interesting (if somewhat short) report on splogs, which you can download here - email and name registration required to download this PDF. Matt Galloway surmises that combined, these two reports might indicate contraction in the blogosphere. Intuitively, I think that's not at all the case, but I do think that Matt is pointing at a phenomenon that is under-examined: the growth rates for splogs are significantly higher than for "real" blogs, based on the data I get to see.
