Short UINs are prized by some ICQ
users. (See, for example, Us low UINs have to stick together.
What's truly amazing is that a UIN of five or six digits can be bought outright on eBay. In one auction, someone paid $305.00 for a five-digit UIN!
This sort of thing isn't limited to ICQ; some personal ads in Manhattan say "(212) only please", even though the area codes are overlaid and therefore 212 says nothing about location.
But it's pretty damn sad anyhow. Repeat after me: It's just a number.
