Less than a week ago I discussed the prospect of a killer feature on Facebook that allows you to differentiate between various categories of your friends. Within days, Facebook added two new API methods to their platform: friends.getLists and friends.getListsMembers. Watch out LinkedIn, Facebook is gunning for you!
While these two new API calls are unreleased, I seriously doubt Facebook would add these to the development sandbox without being near completion. This could signal one of two things: Facebook is adding the killer feature or Facebook is adding a feature similar to Slide’s Top Friends application.
