BTW, is there any reason Google can't supply a slapped account with some kind of report outlining the problem(s) with your site? I know I'm dreaming here, but it seems like the least they can do for paying customers.
Anyway, the real purpose of this post is to discuss what people have done to recover from the slap. I'm hearing some information that the old technique of getting a new domain and just adding some new content is not enough this time.
So, if you've succesfully recovered from the slap for over a week or longer, please share what you've done.
