We've been doing some housecleaning (in preparation for rolling out a site upgrade) and it's been some time since I dug in and updated our list of top political blogs. Indeed, an embarrassingly long time. Sorry!

Anyway, here's a fully revised and up-to-date list of the top 50 political blogs, along with two top 20 lists for the top liberal and conservative blogs. All three lists are based on Technorati's measure of "authority," which is the number of incoming links to the blog for the last six months. Let me be the first to emphasize that this is hardly a perfect metric. The number of incoming links shown by Technorati sometimes varies, which is a quirk of how their databases work. And not all incoming links are created equal, but Technorati has no way of saying so. In other words, please don't obsess about a blog's exact position on these lists, as bloggers like to say, your mileage may vary.
