For some business models I lack enthusiasm, especially at a certain scale. Webvan was one. In 3 tweets is decent capture of both my low appreciation for, if another’s foreseen long-term viability of, the grocery delivery start-up Instacart.
Also, research indicates most groceries and other items in a home were brought there by the lady of the house–the home’s “primary shopper.” Purchases she didn’t make often still required her approval. I know her. I am her. She’s picky. She won’t outsource everything.
