ORKUT : Youth Icon of The Year

Orkut is the youth icon of the year :-
Orkut was launched in January 2004 by search company Google.
Features
A user first creates a "Profile", in which the user provides "Social", "Professional" and "Personal" details. Users can upload photos into their Orkut profile with a caption. Users can also add videos to their profile from either YouTube or Google Videos with the additional option of creating either restricted or un-restricted polls for polling a community of users.

Scrapbook
"Scrapping" is popular among the Orkut community as a form of offline and online communication. In December 2007, the ability to pop up alerts immediately when a scrap is received was added, adding instant messaging-like capabilities to Orkut.

Communities
Another feature of Orkut are "Communities". Anyone with an Orkut account can create a community on anything. One can post topics, inform users about an event, ask them questions or just play games. There are more than one million communities on Orkut with topics ranging from pizza to pasta. The first five communities on Orkut were started within 24 hrs of the site's launch. There were a total of 47,092,584 communities on Orkut as per March 24,2008 4:25PM IST (+5:30 GMT). With the recent addition of the search topic feature in the communities, some Orkut communities become the de facto source for the website links to movies, e-books etc.

Other miscellaneous features
Users have options to rate their friends in the order of "Best Friends", "Good Friends", "Friends", "Acquaintances" and "Haven't met". Further, each member can become fans of any of the friends in their list and can also evaluate whether their friend is "Trustworthy", "Cool", "Sexy" on a scale of 1 to 3 (marked by icons) and is aggregated in terms of a percentage. Unlike Facebook, where a member can view profile details of people only on their network, Orkut allows anyone to visit anyone's profile, unless a potential visitor is on your "Ignore List". Importantly, each member can also customize their profile preferences and can restrict information that appear on their profile from their friends and/or others (not on the friends list). The highlight feature is where any member can add any other member on Orkut to his/her "Crush List" and both of them will be informed only when both parties have added each other to their "Crush List".
When a user logs in, they see the people in their friends list in the order of their logging in to the site, the first person being the latest one to do so. Orkut's competitors are other social networking sites including MySpace and Facebook. Ning is a more direct competitor, as they allow creation of Social Networks which are similar to Orkut's communities.
There is Birthday reminder on the home page of each user,which shows upcoming birthdays of user's friends.
Security and safety
In 2005 dozens of communities' ownership was hacked by a Computer Security expert known as Shamsher Terror to demonstrate the undiscovered security vulnerabilities. A similar feat was performed by a Brazilian hacker called Vinícius K-Max , using a cross-site scripting (XSS) vulnerability. Eventually, various phishing sites were developed with the intent of stealing other people's accounts and communities.
In December 2007, hundreds of thousands of users accounts were affected, using another cross-site scripting (XSS) vulnerability and a worm developed by another Brazilian hacker. A user's account was affected when the user simply read a particular scrap containing an embed which caused the user to automatically become a part of a community on the site, without approval. The affected user's account was then used to send this scrap to everyone present in the user's friend list thereby creating a sort of a huge wave. This vulnerability was eventually fixed within a few hours after being reported.
