With the passage of time previous MySpace’s desktop-only instant client, MySpaceIM, is transferring in-browser. It is under planning that it will be rolled out to other English-speaking countries (including the U.S.) in the coming few weeks though the company is beta-testing it with Canadian users at present.
From the Web-based Meebo, MySpaceIM is already accessible. At the bottom of the browser window in its own toolbar the new MySpace is attached and is very much akin to the Facebook Chat.
Also it can be popped out into its own browser window. Not only this you can also IM with MySpace users who aren't on your friends list, something that I don't quite understand the benefits of, or you can toggle the privacy settings to always be "invisible" or to only accept IMs from people you've already approved as friends.Whereas MySpace owned by News Corp is not ditching its downloadable desktop IM client. It is said that they both are interoperable.
Though it is suspected that Facebook users have simply turned off Facebook Chat still a younger, more entertainment-focused feel, MySpace may have better luck with in-browser IM. It is like a planned scheme to loose the membership-count battle to Facebook many months before. And finally MySpace is making its efforts to increase its edge in user engagement.
