Richard Hulse, New Media Manager at Radio New Zealand (and a MySource Matrix user) posted an interesting article today about the uptake of Firefox 3. The post has some graphs that clearly show a large shift to Firefox 3 for visitors to the Radio NZ website. That prompted me to check my own statistics for the MySource Matrix website, which are very similar.
Like Richard, I didn't see any noticeable difference in the number of users using Firefox, but there was a definite shift from Firefox 2 to Firefox 3 around the middle of June.

Firefox users certainly heard the call.
