Remember my big rant last year about the horrible experience of updating Adobe Reader on my computer? Adobe is not improving things. (As John Gruber puts it, "Dear Adobe Reader team: We're laughing at you, not with you.")
More interestingly and completely unrelated, there's now pretty serious evidence that Polynesians reached the Americas before Columbus did (but not before the Vikings), bringing chickens with them. But, since there were already people here, and since Polynesians preferred to settle only uninhabited places, they probably just went home after that.
In any case, it looks like Polynesians crossing the ocean 600 years ago were more on the ball than the people building Adobe's installer software, who should also turn around and go home.
