I have become less and less interested in Facebook, personally speaking. We got it at my college in...early 2005 and it was absolutely viral on my campus, I was working a long shift at the library that day and every other person who walked through the door was saying, "We got the Facebook!"

But, yeah. I don't think most people have any conception of the persistence of information on the web. Actually, no. I know most people don't have anywhere near the internet/tech savvy of the average DW user. (see icon)
