This happens with every Google update - when a site owner feels their site was downgraded in Google, they blame the most talked about and recent Google update. Heck, I even see people blame the Google Sandbox for their site ranking issues.
With Google Panda, this is no different. Every time there is a Google shuffle or a site drops in the Google search results, more often than not the webmaster will call it an issue with Google Panda.
A new WebmasterWorld thread has some folks claiming there was a Google Panda update recently while others say no.
Could have been, who knows. But now, whenever there is a Google shuffle of any kind - fingers point at Panda.
Who is to blame? Google? Me? You? We all are.
Who wins? No one really - it doesn't really help either way.
The best SEOs are able to analyze the site's issue, target a fix and get the site working well in Google - be it Panda or a Sandbox. :)
So don't just assume it is Panda - give yourself some credit and dig deeper.
