Technorati is the authority on what’s going on in the world of weblogs. The power of weblogs is that they allow millions of people to easily publish their ideas, and millions more to comment on them. Blogs are a fluid, dynamic medium, more akin to a ‘conversation’ than to a library — which is how the Web has often been described in the past. With an increasing number of people reading, writing, and commenting on blogs, the way we use the Web is shifting in a fundamental way. Instead of being passive consumers of information, more and more Internet users are becoming active participants. Weblogs let everyone have a voice.
