As a product manager (PM), I am also keenly aware of just how little comprehensive guidance there is on what it means to be a great PM, which led me to starting an open-source list of resources to help aspiring and more veteran PMs learn the craft. I like blogging and people having their own personal spaces on the Internet outside the scope of big platforms (you can follow this blog in your RSS reader) so I started an aggregator of great personal blogs to follow. I previously explored the Halo API fairly extensively, maintaining OpenSpartan - it was a hobby project that was all about tools to help analyze Halo data.
