Typophile is a great site, I agree. I've lost numerous hours there.
Some others:
You shouldn't miss out on Spiekermann's blog. I love his designs, his insights, and his standup routine, er, I mean, his lectures. I've heard him speak a couple of times and he's dryyyyyly funny along with being very articulate and, like I said, insightful. His blog is at http://www.spiekermann.com/mten/.
The H&FJ site is wonderful (typography.com) if for no other reason than to check out those revolving images on the home page - wonderful lighting effect on those flat images.
A new site I discovered just a few months ago is http://ilovetypography.com. A really wonderful site. I think it's only been around a couple of years. Interviews with Jean Francois Porchez, Ellen Lupton, and - wait for it - a link to a lecture by Mr. Spiekermann (look down the list of Recent Articles for Sunday Type: Spiekermann).
All for now. Check them out. Good stuff.
