What I see matches your screens. The font renders poorly on Windows (Chrome & Firefox), on 2 different PCs (one Vista, one Windows 7). Cleartype is enabled (default). I've seen similar problems with web fonts before, but this is especially bad (probably exacerbated by the small font-size) so you're not alone. Shame, as it detracts from the rest of the design which is pleasingly beautiful.

Back on-topic: Very interested in this release, router sounds especially promising. Hope to see some docs on that soon.
