What are your absolute favourite pieces of web-native typography? Not flash, graphics text or anything other than CSS.
My current favourite is the Tufte-esque restraint of http://tesugen.com/irrational, closely followed by Venusburg and Interconnected.
Suggestions below please!

Of course all these look twice as good in OSX… the examples you cited do tend to look a bit ‘thin’ in a certain older OS.
Love Interconnected and WhatdoIknow…and yeah, they all look that much better in OSX.
Dig Airbag(http://www.gregstorey.com/airbag/) as well…
I like Dean’s http://www.textism.com. [And my own http://www.marquis-kyle.com.au/mt/ of course].
