Here's a pie chart showing what browsers people visiting this web site are using. It looks like Firefox is catching up with Internet Explorer, though you'll have to take into account that my (Firefox) visits to the site are counted here, and I visit it and refresh it to check that my posts have gone up OK and to check for comments. Even so, quite a few people are using this new search engine. [Late edit: I meant browser, not search engine. Maybe I should read my posts before posting.]
That's right. It's fascinating.
