I received this link through Brent Ozar Unlimited’s weekly mailing list (if you’re a SQL geek at all, sign up for it by registering for their SQL First Responder Kit!).

The short version of Justin’s blog post is that Google is simply miles (kilometers for those of us not using Freedom Units) ahead of Apple maps, and everyone else. He delves into the level of data and derived information that Google has access too, which really shows how far ahead they are versus the competition.

Definitely worth the read, especially if you want to feel inadequate about your own data collection and analysis skills and systems.
