One thing about blogs that is so fascinating is the interlinking. There are millions of people keeping active blogs, and bloggers often tend to look at other people's blogs. When they see something they like in their favorite blogs, bloggers will often link to and comment on it.
All of this tight interlinking has created a phenomenon known as the blogosphere. The blogosphere consists of all the cross-linked blogs. Once you arrive at one blog in the blogosphere, it will often have links that connect you to many of the other sites in the blogosphere. You can bounce around in the blogosphere for years if you like that sort of thing.
Many blog readers enter the blogosphere and find one (or a few) bloggers they really like. For example, you might have a blog you use to keep up to date on the latest technology, and another to keep up to date on the latest news. The blogger is acting a lot like a DJ on a radio show, choosing stories, links and/or snippets just like the DJ chooses songs. People who like what the blogger focuses on each day come back and read that blogger every day or so. Celebrities have also gotten into the act, creating blogs as a way to interact with their fans.
