I constantly hear has-beens saying that because of some personal experience or their general malaise about something, an entire industry/area/field is "over" Wired wrote about the death of the internet. People write constantly about the death of websites and the rise of apps. Or about the death of hardware and the rise of software being all that matters. Or the post-computer age. Or whatever crap they're trying to hock or stock they're trying to inflate. They're all wrong. Most of them just come off as trying to blame a changing environment for why THEY didn't succeed. In Yammer's case, it sounds more like "see, we did the right thing by cashing out and becoming a part of a giant corp, because we're just fleeing a sinking ship" rather than "we were getting out ass kicked by other social networks and this was a lifeline".
