The Comics Curmedgeon is a pretty neat blog that comments on daily comic strips, doing so in a snarky, smart-assed way...which of course, is right up my alley.
I never cared much for Mark Trail until reading this blog (which I found via wonkette, another fine blog), which pointed out the startling, head-shaking, truly bizarre happenings therein. The current "plotline" involves crooked county commissioners, an airport, and some ne'er-do-well named "Buzzard" and will most likely end with Mark breaking out the fisticuffs to solve the problem.
Oh, you can read most of the comics online at the Houston Chronicle's website. You can also set up a customizable page with just your favorite comics, too.
