Sad but true, if my computer and internet were still working I would check Facebook and the Escapist to see if anyone else survived.
After destroying the refresh button checking for updates, I would honestly probably grab everything I could (all the important stuff... my iPod, iPod charger, headphones, my 360/PS3/PC and all my games, clothes, acoustic guitar... you know, the important stuff) and pack it into my car and just drive. Look around, try to find food... it would be a pretty boring post apocalyptic movie.
