I've decided to take the plunge and move on to publishing at http://abstractioneer.org, powered by Blogger. Since I'm the tech manager for Blogger it seems only fitting, and we've recently been adding a whole host of cool features that make it more and more attractive (OpenID commenting being just the latest).
I also have a semi-new Feedburner blog feed; some people were already subscribed through this feed, so you may notice no disruption in service as I re-point it at abstractioneer.org... just a moment... there! (http://feeds.feedburner.com/aol/SzHO). Feel free to re-subscribe there, if you are in the mood.
