I registered that domain some time ago, primarily as a publishing location of various SQL Server articles that I've self-published. Since then I've gotten a tonne of interest by people who'd like to contribute (people who know me and like my stuff), mostly people irritated seeing it sitting idle (I've had far too much on my plate for a while).

As such, today I switched http://www.professionalsqlserver.com over to a MediaWiki (the powerful platform that Wikipedia runs atop), though it'll take a while for the DNS change to fully propagate. It should make for interesting times, and I hope to learn a lot about online collaboration, and about the MediaWiki platform. Right now it's a bit of a mess, but I tend to exploit and master these things pretty quickly, so watch for it to get really exciting quickly.
