It's amusing/saddening that significant numbers of commenters assume launch == promotion at Google today. The vast majority of promotions at Google are for impact on engineering efforts that never reach the public's attention.

Boring, no-comment-worthy stuff like "cut CPU usage by 10% in the service", or "reduced out XX of support toil", or "reduced attack surface of YY by ZZ".

"Launched product AA" is pretty rare as a promo argument.
