Technology news aggregator Techmeme has launched a new feature today, the Techmeme Leaderboard.

Up until now Technorati has maintained one of the most useful blog ranking services around. By no means is Technorati's Top 100 an exhaustive list of popular blogs. But by measuring web site "authority" and the number of links other bloggers make to a site, Technorati's list has long been looked to as a way of determining which blogs are most influential (which is not the same thing as determining which blogs get the highest traffic).

Techmeme uses a proprietary algorithm to determine the day's hottest news in the blogosphere. Unlike Technorati, some of the day's top stories on Techmeme will often come from mainstream news sources like the New York Times. But if you want to know what bloggers are talking about, Techmeme's front page is about as reliable a resource as any.

The Techmeme Leaderboard is a list that shows the top 100 based on stories that made the Techmeme front page in the last 30 days. In other words, if you break news, or write about news that someone else broke often enough, you have a good shot of making it onto this list. Will this list be more accurate than Technorati's? It's hard to say. But if you're looking for a hundred good blogs to add to your RSS reader, we're pretty sure most of the sites on the Techmeme Leaderboard are worth reading.
