Simple. It's you vs. the game, not some 'everyone as a collective must beat the odds in order for anyone to win' scenario as Slip puts it. The thread is titled as it is to have a central 'point' to come and talk about the game, and members are encouraged to come here to this thread to do so. it's not literally all of GTP vs. Wham!.
If it wasn't a central 'point' for it all, we could very well have numerous threads and/or posts by various members documenting and sharing their efforts, which would lead to a lot of spam for OT - and frankly - clutter. (It'd be much like people documenting their GTS 'careers' in status updates, actual pointless ego-stroking)
I originally came to state no intention of playing this year after beating the game last year, and wish others the best of luck. I then saw something in the OP I didn't like done in it's cheeky manner, and just pointed it out. I would've been fine to leave it there, but TB had to do some ego-stroking crediting, and the rest is history.
