Blogga what? Blogga who?

I was checking the Drudge Report headlines after my lunch meeting this afternoon, and I scoffed aloud at the headline that Michael Isikoff's (Newsweek guy who wrote that story) resignation would not be accepted. My officemate, an affable and well-meaning, but really quite clueless guy, asked me whence the scoff. I explained the story to him (of which he had not heard, incredibly), and said that the blogs were all over Isikoff. "What's a blog?" he asked.

After explaining it to him, I wondered how many people who consider themselves to be well-informed don't read blogs. I wonder how many don't even know what they are. In my opinion, obvs, one simply cannot be considered well-informed these days without regularly reading some big-name blogs.

My question to you: Did you know what a blog is before you started visiting my site? Has this site got you to read any other blogs? Do you think they're important? Do you know the role that blogs played in the recent CBS News and Trent Lott affairs? Please satisfy my curiosity and post your experiences with and feelings about blogs and blogging (not necessarily this particular blog, but whatevs) in the comments. Blog blog blog. Blog-blog blog blog. Blog.
