Technorati channels

Our site is organized by topical channels: business, entertainment, lifestyle, politics, sports, and technology, plus search and Blogger central. Underneath it all is a near real-time system called the Percolator which looks at linking and attention patterns of posts, who wrote them, who's linking to them, the rate of their popularity growth and many other factors. We use this information to determine what’s hot now and what’s gaining in attention — effectively the pulse of the blogopshere.

Rising news story and rising blog post

These show the blog posts and mainstream media stories getting the greatest attention from other bloggers in a topical area right now. The percolator tends to update these around three times an hour; enough time to track trend and attention data, and short enough to keep pace with the blogosphere.

More rising blog posts and more rising news stories

These highlight other fast rising posts or breaking news stories by channel, giving users a glimpse into what bloggers are paying attention to most in each of our topical channel areas.

Today in photos

Is a visual record of what the blogosphere is looking at today, in the form of a feed of the photos embedded in topical posts.

What is Attention?

Technorati measures Attention by calculating a weighted rank based on time, number of links, rate of new links, Technorati Authority, and the Technorati Authority of linking blogs. Attention changes over time, so something that was getting a lot of attention this morning may be much less interesting later in the day. A Technorati attention-based view allows you to concentrate on those items that are gaining the most attention now, even when they were created hours ago.
