Lines from the past occasionally float to the surface. Here's one I have been thinking about lately: "OK open systems beat great closed systems every time."
That one came from Scott Kurnit around 1994-95, when he was VP/marketing for Prodigy. His company, originally a joint venture of CBS, Sears and IBM, had built a closed system (great in its day) that was in the process of getting its tail kicked by a bunch of little startup companies that run by people who had no clear idea where they were going.
These startups were pushing open standards: TCP/IP, HTTP, HTML.
