Flow is the feed. It's the posts and the tweets. It's the stream of daily and sub-daily updates that remind people that you exist.
Stock is the durable stuff. It's the content you produce that's as interesting in two months (or two years) as it is today. It's what people discover via search. It's what spreads slowly but surely, building fans over time.
I feel like flow is ascendant these days, for obvious reasons - but we neglect stock at our own peril.
It's all true. After this page, the most popular parts of this site are my Zoom Teeth Whitening Caution (it hurts!) and Eating Organic on a Food Stamp Budget which, people tell me, they "read like a novel".
Robin may overestimate the rate of flow which is necessary to keep you on the radar, but she is absolutely correct in understanding that it is a necessary mix. (via @jayrosen_nyu)
