I'm integrating the old MediaWiki based site and the old blogger site into one new site here at Squarespace. It's cheaper and better and quite frankly less of a maintenance headache.
Squarespace is kind of fun ... but also now that I'm doing the work I realize I actually put more effort into MediaWiki than I realized. Plus I have references to files all over the place. Lots of links to fix ... so many that automated solutions are being researched.
