I remember the good old days of domain squatting

At least you had to pony up a few bucks per domain name back then.  Now there's Twitter squatting.  It's fairly predictable, really...  Every single letter TwitID is taken.  Common surnames...  taken.  Common words...  taken.  Apparently, you don't even need to use a legitimate or at least legitimately unique e-mail address to do it.
