traffic is up more than double today

That's something I don't like to see on the front end of algorithm updates. Our evergreen sites haven't been negatively affected since the end of summer 2012 but here's my personal observation for older "satellite" sites we never cleaned up: refreshes are about a 7 day process; First day they shoot way up because higher traffic competitors (more page 1 SERPs) get hit first allowing some of our sites to see sunlight above the page 1 fold; by mid week our sites get hit, and things normalized by the end of the 7 day cycle, generally with our sites losing a few positions or more.

The updates/refreshes that were beneficial were those when a site suffered at the beginning of the update. That may not make sense being that it's an more of an emotional observation than logical but I'm in front of the screen nearly all day, every day and see these things; whether I interpret and communicate them well is debatable.

Part of the above concept was made partly from points Matt Cutts made about the crawl process in this video [youtube.com...]

I have this feeling that not so many care anymore

Replace "care" for "worry" and that's me. It used to be like a "Whack-a-Mole" game, when we stopped making sites to pop up here and there we stopped getting whacked.
