Take a second to look at your blog's browser stats. If your blog is like most others, a good share, if not the majority, of your users are getting to your blog with Firefox as their browser. It's early for the Garden, and I definitely skew the results, but so far half of our visitors are using Firefox.
And NONE of them are being counted by Alexa.
Alexa only counts users that have the Alexa Toolbar installed, which many people don't realize. Now bloggers ARE more likely to use the toolbar than the average user, but at the same time, they are also more likely to use Firefox.
And currently Alexa's toolbar is NOT available for Firefox, only IE. But what would happen if Alexa announced today that its toolbar was available for Firefox? Can you imagine how quickly this toolbar would be adopted by bloggers? Traffic patterns for blogs as a whole, according to Alexa, would begin to surge almost immediately.
MSM is already beginning to notice the increasing traffic patterns of blogs, but the kicker is, those patterns are calculated with a toolbar that only supports IE, which is used on the whole more by surfers to MSM sites, not blogs. If the advantage flipped, and if Alexa embraced Firefox, then suddenly the advantage swings to blogs in the traffic-wars.
The potential impact to the ultimate future of blogs would be huge if Alexa ever adds Firefox, the blogger's browser of choice. We'll see what happens.
