19% of Instapundit Readers Use Firefox
An impressive example of a non-techy site receiving a very large amount of Firefox visitors. While there's something to the argument that those who get their political news from a Weblog are likely to be more tech-saavy; I think that the more tech-saavy are reading Instapundit via RSS, which is unlikely to be counted in his stats. For instance, I read Instapundit using Firefox, but through Bloglines.
