Anyway, Sloan has this really interesting post from 2010, discussing the distinction between stock and flow. It starts with social media, but applies to all of life:
I feel like flow is ascendant these days, for obvious reasons—but we neglect stock at our own peril. I mean that both in terms of the health of an audience and, like, the health of a soul. Flow is a treadmill, and you can’t spend all of your time running on the treadmill. Well, you can. But then one day you’ll get off and look around and go: Oh man. I’ve got nothing here.This would be "stock", that post. As opposed to my linking to it, which would be "flow." It's worth a read either way.
