Orkut Social Networking Features
Orkut works and runs just like any other social networking site. You create a profile, build a network of friends, and then interact with the community by posting updates about yourself, uploading photos and videos, and practically everything else that you normally do in a social networking site. Nothing special here, really.
One notable feature of Orkut is a facility for integrating Gmail's Instant Messaging service- GTalk. That means you can chat directly with your Gmail contacts right inside your Orkut profile page. You can also create community polls from time to time to ignite activities in your Orkut update stream.
Another feature of Orkut which I find cool is the facility for rating your friends. You can indicate whether a particular friend is "Trustworthy", "Cool", or "Sexy" on a scale of 1 to 3. This is aggregated in terms of percentage.
One feature which you may not like is that Orkut allows everyone to see your profile even if they are not in your list of Orkut friends. If you're a Facebook user, you might not like this feature. But if there is a particular person that you don't want to allow viewing of your profile, you can simply put them in your "ignore list."
Other features of the Orkut social networking site include profile customization, profile restriction, a "Crush List", and listing of friends by the order of their login time on the site.
MySpace and Facebook? Actually, Ning is a more direct competitor, as they allow creation of social networks which are similar to Orkut's communities.
