It means Support for Support. Its usually used by layout sites to help get more users to use their layout code on social networking sites. Lately it has evolved for use by social networkers as a way to add more friends to their friends list. For example, on MySpace someone may post a bulletin promoting another persons page with reasons to add and not add them. In turn the person will return the favor resulting in both acquiring much more new friends or "Add Requests". This process is known as Support for Support (s4s) or W4W.
