I have a tendency to aproach with caution anything that starts off 'Lol'.
There are one or two people I know who use it along with 'AOL' but they are also unlikely to send links without any reference to what the site is. (and I don't use Twatter). Those who do use 'Lol' a lot are also those who frequently send chain-mail and pictures of cats with accompanying 'Awwww, so CUTE!!!!!'. WTF do they need knob-pills for? I'd rather they didn't reproduce.
