Not only that, but its a great way to learn about other things. Someone once said that the Blogosphere is the digital equivalent of a room full of loud drunks, each willing to tell you something or share a story if your willing to listen. A site like Technorati helps point you in the direction of Blogs that you might be interested in.
A look at what was popular on Technorati was interesting. The top searches were predominately tech related, except for Barack Obama (6) and Lindsay Lohan (11). Obama, I can understand. But Lohan being on the list just shows how crazy we all are for celebrity gossip.
