Well, think of it like this. Suppose you've been online browsing Aberdeen-Music for a while then you decide to go to the bathroom for a wank. It takes you longer than usual to cum, and by the time you return to the computer, 15 minutes have elapsed. 'I wonder what scintillating posts have been made in my absence?' you think to yourself. Normally, this question could be answered in seconds by simply going to the Wasteland and hitting refresh. Now, however, you've got to trawl through 15,0000,0000 separate forums until you hit the jackpot and find the one that's been posted in. It's like trying to find the wet patch on a leaky water bed.
