Orkut was a social networking website that was launched in 2004 and shut down in 2014. It was one of the first social networking sites to gain widespread popularity, and at its peak, it had over 300 million active users. One of the features that made Orkut popular was the ability to check if someone was online.
There were several ways to check if someone was online on Orkut. One way was to look at the person’s profile page. If the person was online, a green dot would appear next to their name. Another way to check if someone was online was to send them a message. If the person was online, they would receive the message immediately. Finally, you could also check if someone was online by looking at the “Active Friends” list on the Orkut homepage. This list showed a list of all of your friends who were currently online.
