It will be the most senseless question if anyone asks you whether you have a Facebook account or not, because Facebook went such viral into public, that if at all the question like basic necessities of human being is asked to a common person, it wouldn't be a surprise if he includes Facebook along with  the food, clothing and shelter.

But I bet few of the things which are going to be discussed in this article are definitely not known to many.

1. The reason behind Facebook is blue because Mark Zuckerberg red-green color blind. The best colour he can see is only blue.

2. When you are logged in Ffacebook and browses some other sites too, FB can easily track all those sites. So always check that you sign out FB, before you open any confidential sites or your personal profiles.

3. Almost 600000 hacking attempts are made on FB everyday.

4. Not only English, but FB can be used in pirate language too.

5. The like button was originally 'Awesome' in the beginning.

6.Just like the bank account, even FB account can be carried on by legacy. That means it is possible to set who will be able to manage your FB account after you die.
