It's not a PR position. I don't work for corporate communications. I work for the search team. I'll be sharing more about the role after I have more time at Google and shape it more. But it's definitely not PR.
If I were still at Google, I'd send you a welcome email and point you to the few things that I thought you got wrong in the past (mainly due to lacking the same context as those on the inside... now you can be the one biting your tongue). Quite a few of us paid attention to your writings. They were always among the most insightful, comprehensive and accurate, even when negative.
In some way, your hire might be a bit of a net loss, because now that you're on the inside, you're no longer going to be considered a neutral third party and I'm not sure that anyone out there writes as well as you did until June.
PR: "those at Google who work hard on search each day"
James Damore worked on the search team. We all know how much his feedback was appreciated by Google execs. Personally, I will not consider trusting Google again unless and until Larry and Sergey issue a public apology to James and seek to make amends. That's my feedback.
