Scobleizer quotes some interesting statistics: Microsoft is gaining server market share because of blogs (and wikis). Though some insightful comments modify the numbers a bit, the increase is still large, and shows that Microsoft can make a dent in that market by doing what they did on the desktop: Offer functionality that is "good enough" and relatively easy for the end user to set up. At the very least, it is in indication of blogs becoming a "must have" on any web site.

To respond, the open source community would have to go from pluribus to unum in terms of user experience, configurations and setup. I doubt that is going to happen. Wonder which segments of the market Microsoft is gaining in?
