Wikipedia is a nice website with all the information and knowledge about different stuff. I browse it mostly for geographical contents like countries, places, and cultures.
Myspace used to be the best website for social networking but it has become more artist or talent prone. It is not purely a social networking website anymore. But it still is in competition with Facebook.
After reading reviews of Goodread on SiteJabber, I paid a visit to the website. It is indeed a very good website for book lovers. It is going to be my preference for books now.
I have my only social profile on Facebook and its worth it. I have read people talk so much about privacy issues, I myself is now a little confused. Otherwise its fun.
