Inspired by Chris Petrilli (and also by looking at the URL's of some other Movable Type weblogs), I've applied an archive redesign. The new design yields nicer looking URL's, such as archives/2003/04/14/comparing_zwiki_code_bases.html instead of archives/002342.html. Granted, the second path is much shorter, but the first one is much better at conveying intent. I especially feel this is important for long entries such as the "Comparing Wiki Codebases" one.
I don't know if I'm going to bother applying the SkunkWeb stuff that Chris does to do redirects from old archive entries to the new ones. I'm awfully busy lazy.
Update: Chris applied the rewrite rules for me, so old articles will lead to new ones. This is done via SkunkWeb, and Chris writes up some details here and here.
