Where Have All the Bloggers Gone?

When I first started blogging, it seemed that there was so much life on the blogosphere. It's dwindling, friends. I know several people who lurk on my blog but don't want to get involved in the blogosphere. When I first started blogging, there was Chance (as a commenter and blog-reader but not a blogger), Aaron, Peter, John, and Beniy. They've now all gone for their various reasons (I'm not saying they're bad reasons. They all have responsibilities.) . It's lonely here.

Why have so many people left?
