Jam Factor: 8.5

About to head home for the night when I got a text message that traffic was heavy. Google'd "Traffic" to see what came up.

First result: Traffic.com - a Web 2.0 ajax-y site that looks fun, loads quickly and let's you customize your map view to get the most clear cut details on Traffic in your area. Complete with "My Traffic" personalization tools, alerts and 'send to friend' features, i think this one might earn a spot on my coveted firefox quick link bar.

My favorite part of the site: Jam Factor Explained
