I was very impressed with this post until I went to the "opentypography.org" site and tried to read the opening paragraph. The font was a nice size and beautifully laid out. It was also a light grey color that (in my opinion) seriously compromised its readability because of its lack of contrast. Having beautiful typography is a worthy goal; I'm just waiting for every site to have satisfactory readability.

(And, yes, I do know about the Readability bookmarklet. I'm just hoping that some day I won't need it.)
