Today I am chatting with my friend Mari Mundo of @mariplansalist about why - why do we share what we do online? Why do we choose to use what we do in our planning systems? Why do we follow or unfollow people? I've been doing a lot of thinking lately about why *I* do what I do, and in this two part series Mari and I explore the question of "why?" further (as well as chat about a bunch of other stuff, naturally).
