I was in Search from 2009-2014. Worked on a bunch of projects - 3 visual redesigns, the Authorship program, some miscellaneous infrastructure & internal research projects, 3 interactive homepage doodles, about 1/3 of the easter eggs you see on Wikipedia's list of Google easter eggs, loaned out to GFiber and G+ for their launches, a few other things. It was already a big company by the time I got there, but I had the pleasure of working with several folks who'd been there since it was just a couple hundred people. It was also a pretty interesting time in its history - the first half of my tenure was when Bing was still considered a scary competitor, so we pushed out a lot of innovations in a short time period - and I straddled the Eric Schmidt / Larry Page CEO turnover, so had experience under both CEOs.
Some day, maybe. For now, I'm much more focused on getting my next great adventure off the ground (which I'm also not really seeking publicity for...my cofounder and I are trying to go directly to target users for feedback and not the general public). Plus, one thing I learned at Google is that there are a large number of employees that do awesome work without seeking credit for it...I was happy to be one of them at the time, and I don't really want to steal the limelight from them.
