I think one of the strengths if I am on the right lines here is that Panda can almost automatically adapt to new spam techniquesas they surface, simply by comparing groups of signals to known low quality sites (by google's definition of course!)

The downside is also present too, some not so low quality sites may exhibit the same signals as those used collectively to define the low quality sites.
