MySpace has moved its outboard instant messaging client into users’ profiles, adding a new toolbar anchored to the bottom of the MySpace browser window. However, MySpace hastens to add that the new client can still pop out, into to a separate window, if desired.

You can choose to IM with any MySpace user, specify that you only want to IM with those users on your friends list or opt for complete invisibility.

Myspace notes that the original desktop IM client is still available and it’s interoperable with the new in-browser version.

Since it’s membership figures were eclypsed by competitor Facebook several months ago, MySpace has been trying to differentiate itself and raise its profile. The new IM client and the recent launch of in-browser photo editing are seen as attempts to appeal to a younger more entertainment-oriented crowd.
