I'm a Yammer user. I'm not head over heels for it, but it's good especially for decentralized operations. I'm in a consulting company and we don't actually talk about projects as much as advertise articles we wrote, software we created, questions, or water cooler type stuff. I see the utility, but $85 Million valuation?! I don't see that. How will Yammer turn a profit with that debt load? Let's say the exit strategy is selling would anyone want to buy it at $400M? If not is it worth that risk for less?
