I run a large site that was unexpectedly affected by Google's "Panda" update. There has been a lot of talk on the subject, but most of it is FUD, and I haven't seen many large sites lay everything out for discussion. This is the first post (of many planned ones) about our experience with Google's "Panda" update.

Hopefully it will generate some good discussion from those facing a similar situation, and help some other people out.
