The News Corp owned MySpace social network has struggled to reign as the top social network in the U.S., only to be recently overtaken by Facebook.

Facebook continues to experience exponential growth and continues to innovate. Facebook firstly launched its Facebook Chat feature, allowing friends to easily chat straight from their Facebook profile, or though a supported IM client such as Digsby (PC), and Adium (Mac).

MySpace is now set to launch its own Chat feature straight from the browser. The new chat service is being tested on the Canadian site and will become available in the U.S. and other areas in the coming weeks. MySpace already has a client-side application, but the browser-based version is a lot more usable and intuitive. MySpace will continue to offer the client-side downloadable version.

The one big and different feature MySpace chat will have is the ability to contact and chat with people who are not on your friends list. You can also change the privacy setting where you would only appear online for friends. Via
