No evidence of any dramatic changes, good or bad. What is very odd, is that Google seems to have selectively removed certain keyphrases from our site (about half), while at the same time leaving very related terms in tact. I've tried to analyze the remaining vs. the removed and can find no rhyme or reason for their actions.
I sent a re-inclusion request and they came back within a week saying 'no manual penalty', so that shines a tiny bit of light on the problem. I am actually fearing another iteration of Penguin because if it goes down like the first, we'll be wiped off the web.
