Facebook.com is the huge social networking site of this time. There are no other social networking site to stand against facebook. I am using Facebook and orkut since 2009 but orkut was banned while facebook is reaching the milestone of popularity.
Facebook is a site to chat/find my favorite people. I like to share my photos and my memoirs with my facebook friends. I like the way of advertising through facebook.
Facebook is also a very good site for gaining knowledge. I am a active member of some General Knowledge groups; hence, I am gathering knowledge by spending few hours in facebook.
The tag and share option is awesome. I like to tag my friends in my picture and like to have comments and likes in my picture. I also use facebook messenger in my mobile for chatting.
I have liked my favorite pages in facebook and getting the daily news and other updates from facebook. I also use facebook for sharing my mouthshut reviews.
