Here are some reasons why Facebook is a Winner,

1.Let me begin with the prime reason which is its charm and simplified sophistication(Except Privacy Settings).There is enough glam quotient in its outlook to attract teens and enough simplicity to engage older ones. There is no option for you to have a desired background or theme, But still it wins hearts with its bluish elegant charm.

2.The next thing is its Social Gaming, which in my view is the biggest thing that attracts teens(In most cases). Farmville is one good example it has millions of people addicted, And the exclusive Social Gaming websites tell the story, And the apps that are offered are good as well, may be not as good and as open as the ones offered by Twitter but still good enough.

3.Next reason is a technical one related to the design of Facebook, All Tech Geeks are aware of the fact that Facebook.com uses 3rd Generation PHP language scripting along with usual Java Script, Now the point is PHP makes the site loading extremely faster(people with slow internet connection will know this).It makes those impatient people and people using slow connection Facebook loyalists.

4.It is not only the largest social networking site in the planet, but also the most stable social networking site unlike Twitter or MySpace,Twitter spills whales when it fails and MySpace goes down so often. But one can't associate that with Facebook, the secret behind Facebook's stability is its 10,000 Servers which is ideal for its 500 Million user base.

5.If you are the one looking for ways to kill time,then there is one easy way, it is to use Facebook, you can do a lot from chatting with sweet hearts to playing games,sending invitations for anything and everything, and there is no limit for fun. Its no wonder that Facebook has overtaken Google in total amount of time spent on Internet.
