Good Resources for App Product Managers part 1

Someone i work with at Opera , asked me recently:
"What are the best (App) Product management blogs to follow ? " 

I found a great list as an answer to this question on Quora :
https://www.quora.com/What-are-the-must-read-blogs-for-product-managers

This made me think its a good idea to capture my own personal answer to this question in a ForTechies post. So here is a list of links to my favorite Product Management resources , blogs, and actual Product Managers that are influential in the field.
Hope this helps other Product Managers discover good resources and pick up new information and ideas to evolve their art.
