So, alas, the template for the old "Hating on Charles Bird" site got corrupted during the recent move to its new digs (which are here, should you need to hate on Charles Bird for some reason), and I can't find the elegant hack I used back then.
I've been mixing and matching from lesser sources, and I'm not getting any closer to what I'm looking for. For now, you can mouse over that hideous "BlogItemURL" business to see the desired result. Any suggestions? Anyone?
[Update: Fixed! Thanks again, Jay Sundahl!]
