Good stuff, Dave! This is definitely nice web type.
As images of type go, I especially like two things you've done here. For one, the blog description is sized and rendered well, giving you mostly sharp stems, punchy serifs and, occasionally, beautifully rendered characters ("R"epresentatio"N").
Careful kerning would yield many more of those beautiful situations, eliminating some antialiasing fuzz because letters will lay slightly differently on the pixel grid. Work from left to right if the text is aligned left, as every increment will affect the rendering of letters on down the line.
The other thing I like is that the blog title is sized such that the thinnest parts of its strokes match the thickness of the blog description's strokes.
This kind of antialiasing control is presently a major advantage of CSS image replacement. Though you're using common faces (Times New Roman, Times), some browsers may thicken or thin the small parts of this identity that really help it jive as a whole.
