I've migrated the blog to Hobix, mostly because Hobix seems to be a little bit better geared toward my uses. It's smaller, less complex, handles multiple blogs well and is not squaking on the edges and depending on sqlite, which is not that well supported on Ruby. But this is still a ruby-based blogware and kind of close to the roots of this blog, Blosxom.
I hope this will make the blog a bit easier to work on. At least the upgrading on a shared host isn't that tricky anymore.
