Time for update. After 6+ months, I have some good news.
I have one site that was SEO for Google. Before Panda, it was on Google search result page 1. After Panda, it got knocked down to page 5.
I took this site and redesigned it for Bing/Yahoo after Panda. I threw out Google guidelines and follow Bing/Yahoo's guidelines instead for this site. I switched from concentrating on making it search engine friendly for Google to making it search engine friendly for Bing/Yahoo instead.
Before Panda, it was on Bing/Yahoo search result page 2. After I redesign the site to accommodate Bing/Yahoo instead of Google, it is now on Bing/Yahoo search result page 1.
In summary, SEO efforts for Bing/Yahoo still works small sites if your site got knocked down because Panda algorithm emphasizes Big Brands over small sites.
This is result for one one site, too small a sample to be definitive. Like to hear from others.
