Technorati is a blog search engine. It searches other Blogs and returns results based on relevancy and immediacy.
How do I use Technorati?
Whether you’re a blogger or not, you can visit Technorati’s home page and enter a search, click on a “top search,” find a blog on a specific topic, or check out some “hot tags,” among other things.
Even if you’re not a blogger and have no intention of becoming one, you can still benefit from Technorati. You can use it to receive up-to-the-moment information on breaking news stories, find out the latest buzz in your industry, or even find out what people are thinking and saying about you (assuming you’re a big enough fish to generate some gossip.)
