They did a Panda update 8/20/12. My traffic went down by 90%. I think the idle hub thing that came out is an attempt by hubpages to combat the traffic problem but I imaging it will take a month or two to work. If it works. Google has pretty much declared war on content producing sites like Hubpages and I think that is what we are experiencing. My guess is the Google gods smacked down hubpages pretty hard.
