Facebook is HUGE

If you haven't heard yet facebook has doubled its size in 8 months from 100 million to 200 million. It is clearly one of the most powerful social networking sites and is constantly evolving and updating itself to keep up with Twitter.

"Facebook has also become a vehicle for broad-based activism — like the people who organized on the site last year and mobilized 12 million people to march in protests around the globe against practices of the FARC rebels in Colombia."

This is just one example of its multiple purposes. A recent conern for people my age 18-25 is that their parents are starting to use Facebook. This is a problem for many users who joined the network when it was just for college students. Now it is an international goliath.
My question is where is the virus that will take it all down?? It is becoming an important target as bussinesses and personal info is flooded through the gates of Facebook.
