I've been on the net for about the same amount of time and I know what you mean, it does get boring. Here's stuff I found interesting recently..
Everest
Discovery channel people climbing everest with head cameras. If your super bored you can watch all 26 hours of it. I was out of breath just watching it.
9\11 phone call
Old one but I'd never listened to it, I soiled myself at the end.
I wasted a day playing "who wants to be a millionaire" over at ya hoo games section, also try their daily soduku hard puzzle, drives you nuts if anything.
