Well, I'd have gotten the time back that I've spent typing over 19000 posts around here...
And watching Zero Punctuation, Jim & Yahtzee, Jimquisition, The Big Picture, MovieBob, LoadingReadyRun, Feed Dump, and Unskippable every week...
I also likely wouldn't have heard of some of the awesome bands I listen to, played some of the awesome games I love now, read some of the awesome authors, and just in general probably wouldn't be quite so in-tune with the current 'geek' culture since this is the only forum of this type I regularly visit and my opinion of most others ranges from pretty low to "You can't spell ignorant without IGN".
Not to say we don't have our own bad apples around here, but I'd either be a much lonelier or much more productive person if The Escapist weren't around to soak up my time.
