I've gone through all of the infamous updates before, been affected to one extent or another, and came out as good as before. This one is definitely different.
Before you go taking a quote of mine and saying how bad it is, wait for the adjustments they are almost certainly going to make to kick in. Every time I can remember seeing a large algo update like this they 'pull the filters off' during the initial rollout, then begin re-inserting them over the next few days.
I agree. Before swearing to get a day job (how many times have we said so :)) we need to wait. Many sites come back within a few days, then new filters come back on, others get caught, filters are adjusted etc etc.
It's obvious that filters are on right now, so let's see google tweak them a bit here and there.
