I think the "shock wave" of Google Caffeine has already reached SEO professionals, they are aware of the new changes in searching algorithms and of the new priorities, I think it's only a matter of time before everyone adapts to the new formula. The first time I heard about Google Caffeine I was reading a notification at outrank.com, I didn't like the idea at first because I knew there's a lot of work in repositioning our priorities but then I realized all these changes are for the best, we can't expect Google to be the same forever.
