Mine is still dropping too. I don't mean this in a bad way, but I'm glad it's not just my site that's being affected. It would be good to know what's going on, but Google would never pay us that courtesy.
I've worked 12-16 hour days for 4 months trying to re-build my site that Google shattered, and I'm earning less than ever. My husband keeps saying "why bother". I'm starting to agree, if I'm going to go broke, may as well be doing something fun while it happens.
