But you can and you should.
Anyone at Yahoo/MS today is (on average) already under suspicion of being 2nd tier and a notch below a Facebooker/Googler. And those Yahoo engineers who stick through this one will tend to be the 3rd tier. They aren't going to see this Yammer thread and they sure aren't going to get hired by a good startup.
So why even bring them up in this thread? We're talking about the good folks left at Yahoo, the guys who are like Jeremy Zawodny and Prabhakar Raghavan, who want to leave before Jerry Yang's company completes its transformation into SCO.
Not the time punchers who don't know what the clock says.
