Farmville and other crappy games like Mafia wars, Restaurant City, and Pet Society are all shit. IMO. (A). Don't get offended. I just use facebook for social-networking. Which is it's main purpose.
Yeah, it was mainly when I realised facebook was just a steaming fresh load of boring, pointless shit that I quit. I now spend that time playing sports and woodworking in my backyard. Im still wasting time, but im much more happier, and I hope others can fill their lives with wholesome happiness like this too, instead of resorting to canned McHappiness.
