I'm on Chrome for Windows and your blog is pretty hard to read. I know that CfW has a ton of font rendering issues, making it easy to overlook some pretty common "jagged font" cases. Here's some more info:

"Using Web fonts in your design requires thorough testing on as many different browsers and platforms as possible, with a close look at various options for rendering text. If the screen display is of poor quality and lacks subpixel rendering, then opt for graceful degradation by serving system fonts to older browsers and OS. Conditional comments are the easiest way to exclude older browsers and operating systems from style sheets with Web fonts. Of course, JavaScript is a more elegant way to detect whether a client’s subpixel rendering is turned on."

My default zoom level in Chrome (nothing crazy, mind you) the 'e' character has no horizontal bar, the ''a' character is not connected, it's also quite jagged. It's funny how such simple things can be so jarring.
