About once a year for the last decade, or more, I rediscover Alexa.com. The folks at Alexa collect browsing habits from folks who install their clever little tool bar widget. They then aggregate that data into the one of the better, if not the best, data on where people travel in the web.

Alexa was bought out by Amazon but it continues to provide a lot of facinating data. These days they display site rankings, rather than site traffic numbers. Bear in mind that site traffic is power-law distributed so the top ten get the vast majority of the taffic.

The stricking change since the last time I played with Alexa is the rise of a number of Korean web sites with amazing traffic volumes. That’s an under reported story!

One of the fun things to do at Alexa is look at the chart that shows site ranking over time, and then contrast sites with each other.
