Today I moved my blog away from IN-Berlin e.V. to my own server as I got frustrated by all those wordpress upgrades necessary lately. So maybe you might want to update your bookmarks. The new location is http://blog.jwchat.org.
On my private server I’m hosting debian’s default wordpress package which should get security updates automatically, thus I’m fine.
Unfortunately I had been using WordPress as of version 2.3.3 while this one is still at 2.0.x and that makes importing my old data a pain in the ass. I’ve written a small perl script which maybe could be of help for you too if you should need a downgrade of wordpress too (I guess it should work with wordpress 2.5.x, 2.6.x also):
