I don't understand the "bad thing" which is happening here. Are we supposed to be so thoroughly invested in the quality of Google search results that it's a personal affront when someone games the system?
Now that could mean a shift as revolutionary as the shift to search engines originally was. Or maybe, because at the moment almost all gaming is targeted at the Google gorilla, it may mean Google loses some relevance and falls back to the pack in terms of market share. Maybe either of those would be good. But why take the risk?
