I noticed that a lot of my Google positions have feel off the first page. I took a rare look onto the usual forums. Everyone is freaking out. It’s been like 24hrs. Shit like this happens. You’ll bounce around after these updates. My prediction is that this is all temporary. If your sites are still sucking after a few weeks, than you can piss and moan.
But at the end of the day, pissing and moaning won’t help you.
