Mobile social networking service Bluepulse is collapsing. Sort of.

The start-up has launched what it calls collapsible messaging, a feature that's supposed to make it easier for users to deal with the huge numbers of messages they receive. Members will see all the messages from each of their groups "collapsed" into a single, one-line thread with the most recent message displayed, Mobile Entertainment reports. A single click will expand the thread so the user can quickly scroll through the related messages.

Bluepulse also made a few changes to its user interface, including displaying the two most recent friends the user messaged on his main message page.
