What I like about Facebook is that in certain applications, it bears no resemblance to real life. Everyone talks about the status updates and the whole reconnecting with people from high school and middle school, but WHAT ABOUT THE GAMES? Only on Facebook can I have a dog (I strongly dislike dogs), a farm (I like the concept of gardening, but dirt on my hands makes me a little crazy), a restaurant (just awesome), and I can also spend time as a fashionista (which I'm not in RL).
On Facebook, I also can own a house with a windmill in the front yard and I have a job in Yoville, but I'm not quite sure what it is I do there (I seem to dance and laugh and joke with various friends -- if only I could turn that into a paying gig in RL!). At various points, I get to travel abroad in something called Kidnapped! and there's also a Mafia War going on. For a while, I was deeply embroiled in a Parking War. I also have a kingdom of my own and apparently my vassals are restless for my return; I don't know what is they expect me to do.
Right now the restaurant game is my favorite. It runs slowly and it's rather high maintenance (actually, all of the virtual life games are high maintenance); not quite feasible for someone who check the site every few days or so. It's like I go and plant crops on my farm, but by the time I return to harvest them, they're all dead. So the only solution is to keep coming back and that, my friends, is the ingenuity of Facebook. After all, you'd feel guilty too if your virtual dog was pawing at you for attention because you happened to have an attack of RL along the way. Now, if you'll excuse me, I think have a war or three to fight.
