I’m now running Movable Type 3.121 here. Major changes include new, smarter URLs for entries (old files remain, so links are not entirely broken) and new commenting system. I now support TypeKey, which is a global registration service. If you register with TypeKey, you can use that id to comment in several blogs. In Gameblog, comments from non-TypeKey users are welcome, but moderated.
This is a minor annoyance, but I’m not doing it just for fun — the comment spam problem is intolerable and this is a full stop for all that nonsense. Signing up for TypeKey shouldn’t be too complicated and if you’re an active reader of blogs, chances are you can use the id somewhere else as well. Of course, signing up isn’t mandatory — you can always post anonymously, it’ll just take a while for your comment to appear.
Movable Type 3 isn’t the most popular option, thanks to the new pricing scheme, but I think it’s well worth the $70 I had to shell for it. There just aren’t any good alternatives to Movable Type. WordPress is popular, but doesn’t work for me because it only supports one blog per each installment. I don’t want to have half a dozen installments, I want one entry point to all my blogs and for all my bloggers. Nothing else does it, as far as I know, except Movable Type.
