Yes, I see the small text now. :) Looks like firefox remembered the text-zoom setting i must have set for some other subdomain of wordpress.com.
To be fair to the blogger, he probably is also a victim here: he's probably reusing a theme (edit: yep, scroll to the bottom) whose designer committed the tiny-text idiocy.
At least he didn't do low contrast and tiny text like most other sites do (e.g., posterous). :)
