Josh Elman:

I spent over a decade as a product manager at a number of different companies.

One thing I realized was how little we talked about the job of product management. I rarely met product managers from other companies.

But I always felt product management was one of the most important functions that when done well, helps make companies and products much better, and when done badly, can really hurt a company and team.

Interesting walk through on the job of a product manager.
