Facebook FarmVille users take to farming like ducks to water

FarmVille is the most popular application on social-networking site Facebook, having attracted more than 56 million users worldwide since its introduction in June. And to what does FarmVille owe its popularity? Simply, it's addictive, according to comments by fans and users on forums across the web.

And First Lady Michelle Obama, the first cultivator of White House-grown fruits and vegetables since the days Eleanor Roosevelt, would likely be happy about that fact. That's because as a virtual farm, FarmVille allows users to manage and harvest crops and generally run a basic farm, as well as visit others' farms, perhaps giving participants greater insight in what it takes to run a real farm.
