A Facebook friend invited you to be their neighbor on Zynga’s Farmville. Since you’ve been curious about what all the fuss and fun is about, you accept the neighbor request and decide to start a farm. Not a lot of direction is provided, you live and you learn and you ask your friends as you go. Suddenly, you find yourself almost addicted to the farming game, yet frustrated at the same time. Nowhere can you find how to earn FarmVille dollars. Your coins rack up, but again, you aren’t even certain why you gain some of them. And XP - you still can’t figure out what it is or what makes this number rise.
