One brain drain versus another

Had dinner with a friend last night who is an ex- Yahoo. Heard this week that Matt McAlister and Greg Yardley are both leaving/have left Yahoo (along with about 10 other people I know.)
Just read this in Wired on Googlers leaving the Big G: “Googlers may as well have targets on their foreheads. The nature of recruiting is that you go after the big companies that have been successful. So any company that wants Google-like success is going to try to hire away from Google.”
So, do you think it’s that recruiters are also calling the Yahoos and hiring them away? (Meow.)
