I'm a product manager currently working at Flipp managing the Flipp Mobile Apps. The usual spiel about these opinions being my own goes without saying.
I enjoy reading anything I think might make me a better manager. I also don't really think there's such a thing as a good product manager that isn't just a good manager.
I believe firmly that writing things down forces you to really understand your thoughts thus the birth of this blog. I can't guarantee you'll learn anything.
