Yes, when penguin affected my site in April, my site was moved to around 950 in the google SERPS for my most competitive keyword. Over 5 months later, my site is now on page 23. Before the penguin update I was on page 2, sometimes page 1.
My domain contains keywords, but it's because these words are what my site is about. Luckily the EMD update didn't seem to affect my site. Then again though, my site isn't exactly ranking well just now LOL.
