Found this at McSweeney's; A 12-YEAR-OLD EXPLAINS THE INFORMATION AGE'S FACTS OF LIFE TO HER MOTHER.
Here's my favorite part:
Now when someone has a lot of things they want to say, they may want to try blogging. Blogging is a kind of social intercourse, and should only be tried after years of experience with the Internet. Think of a blog as a newspaper that people actually read. It's a very personal thing, and you need healthy boundaries. For example, you can't go around blogging about the time I peed my pants when we went to see Ice Age like you told that woman in line at TJ Maxx yesterday. You need to be cautious before you move on to something more serious, like a tweet.
Not sure I dig thinking of this blog as social intercourse since it would make me seem, well, you know, but I can definitely dig "a newspaper that people actually read."
