Popdex - The Website Popularity Index

Popdex is a blog search ranking tool that continually crawls the web to determine the most popular current events sites.

More information about them, from the website:

"Popdex came about because an inflated technological ego thought that a current-events news & link spider could be built in a few days. A month later, after many Mountain Dew filled nights and weekends, an index was born.

Not having added anything "new" to what was out there already, the next step was incorporating the popularity of linking sites into the rankings. Thus if websites A and B are extremely popular, and link to site C, then site C is given more weight in the rankings than a site linked to by sites with smaller numbers of inbound links.

A score is computed hourly and the rankings are updated, with the highest possible ranking out of 100 (like a percentage). I call this technology PopScore."
