I think it's one of several gwt areas-- another is the keyword list-- that's essentially padding, created purely for wmt-internal use. It's got little-or-nothing to do with anything happening in the world at large.
A more useful approach may be the "link:" feature in ordinary search. I've just tried it and am bemused but not really surprised to find a slew of links to me that aren't mentioned anywhere in gwt.
