I don't think you can look at one thing like that, and think that's the problem (or that's the solution) You have to look at everything as a whole. Forest, not trees.
Most if not all my sites link out a *lot* and none of them has ever been hit. Personally, I think it's probably a quality signal to link out to a quality site. But it's only one signal among many.
