Ad Serving Engineering

I got LinkedIn over the weekend with Frank O’Donnell, who managed the ad serving engineering group when I first started.  He’s now at  I still recall sitting with him in conf rooms like Paris (on 16 @ 450), going over major ad serving issues, why we were dropping clicks, like after every 347 days or something.. who remembers.  But it was a barn burner back then!  (Note: this is 2002, so very much in the rear view mirror!)
