The most addicting App on Facebook...

I'm on facebook just about every day. I play chess, mostly with coworkers, and due to my history I also play Wrestler with some regularity. I've also tried and stopped using all the popular apps my friends play.

What I find interesting is that the most common tag line I see for facebook game application advertisements is "The Most Addicting Game On Facebook." While on some level it disgusts me that this sort of advertising works, I am intrigued by the psychology of why it works. Is it because of the nature of facebook and other social networking sites? Is it just human nature? Why is addiction something we would knowingly chase? Is it the man trying to keep us entertained so he can keep us down?

Needless to say, one can spend a lot of time analyzing this simple phrase and why it is so popular. So, in an effort to crowd source with the 1 or 2 people who come across my blog :) I leave it to the comments for discussion.

Only because I mentioned the 2 game apps I use on facebook:
My chess challenge URL is:

And for those of you who wish to see the facebook incarnation of Deacon (the wrestler) may go to: http://apps.facebook.com/wrestle/Wrestlers!show.fb?id=590273940
