Fixed my feed in IE7

IE7 wasn’t working with my feed before… Turned out this was because a WordPress plug-in I use had an error in its PHP file that was causing debug spew to appear at the bottom of every page, including the RSS/atom feeds!  This led to some invalid XML that most readers just ignored.  But not IE7!  I guess they got tired of taking flack for letting messy mark-up slide.

I also disabled a redundant (and I think slow) plug-in and did some database maintenance/optimization that will hopefully speed up the site a little.
