overdue upgrade

so i _finally_ got around to upgrading the blog software on my website this past week. this new version has been available for over a year, but i'm lazy and the old stuff was working pretty well. the main advantages of the new software are that it supports feeds and has more options for dealing with spam. so... i've gone ahead and re-enabled comments for recent posts so you can reply to my blatherings if you feel so inclined.
