Before they were acquired by Google, looker had a bunch of really engaged community support people, and the docs were great for what the product did. There were learning paths for different types of users and tutorials linked to references in a way that made sense. I learned a lot about effective documentation (and looker!) from going through what they had.
Even if 100 US-based community support folks were making $300K in total comp, why would you not spend $30MM to keep your $2.6B acquisition humming along? A bit mystifying.
I think they should keep acquisitions under Alphabet and separate from Google. What is the point of having umbrella corporation if not going to use it?
