I'm slipping but very slowly, down to #7 for our main target keyword. For other terms there is absolutely no movement as if they are below the radar or too small to bother a Penguin.
What is most confusing is the kind of sites that are moving up (bobbing to the surface from way back). They are all of an identifiable type. It looks a bit like an unplanned side effect in the same way as directories climbed out of their pit at the Florida update. Now, in my niche it is review and comparison sites, almost as though Google has decided if people are searching for "search term" they are shopping around and we should give them sites that help them do this quicker. Thereby cutting out the specialist micro sites.
This could possibly not be Penguin or it is just a coincidence that this type of site offers what the sites that have suffered under penguin don't have.
