I've been tracking the browser share at boingboing.net for a while now because it's a pretty good proxy for overall share in the blogosphere. Right now, Firefox is sitting at 52.1% share of boingboing.net's readership and combined with the other Gecko-based browsers, Mozilla's user agent now accounts for more than 55%.
It's also interesting that while roughly 24% of boingboing.net's usage comes from Macintosh users, Safari only accounts for 12.4%. There are no other Mac browsers with >1% share at boingboing.net so I think it's a reasonable interpretation that nearly half of the boingboing.net Mac users are surfing with Firefox.
What kind of numbers are you seeing at your blog?
