Have received a bunch of emails wondering at my absence over last three days. Headed out early Friday and got back last night from a family vacation weekend in San Francisco. Appreciate the concern, but all the alien abduction theories unwarranted -- for now, anyway.

Nice graph from the FirstRain research service showing employee turnover trends at Google and Yahoo over the last year. Red denotes turnover-related losses, and green denotes gains. While both companies have seen losses, the level at Yahoo -- especially in recent weeks -- is daunting. 

Just by way of comparison, I have also included the recently-deceased Bear Stearns, whose losses pale against Yahoo's executive exodus.

[Update] If you're thinking of leaving Yahoo, there is now a boilerplate resignation-letter generation tool out there. Check it here.
