There’s an undercurrent of hostility in the marketing world this week. Google and Apple continue to joust, sending not-so-subtle messages about their intentions. There was also news that teens might not be liking (pun intended) Facebook as much as they once did. Ditto goes for Bret Taylor, Facebook CTO, who is leaving the company this summer. Finally, Dave Winer joins a chorus of folks who are mad at ICANN.

Not everyone was mad though, as we saw two fairly high profile acquisitions in the digital marketing vertical. Congrats to AKQA and Econsultancy.
