Search wiki is a way for users to give feedback to Google about whether a search result is really appropriate for the search terms.
How much you want to bet that this "innovation" has put a loaded gun in the hands of Leftists who can mobilize a whole bunch of people to "down check" atlas and other sites?
In other words, it might NOT be Google directly, but people "google bombing" atlas.
Interesting, I didn’t know that about Google search Wiki. The same thing could happen at Free Republic.
