I interviewed Chris Anderson (Wired editor, Long Tail author) for a story I’m working on about the future of beta as it pertains to the web. While talking, I digressed to the subject of business models, to which he said, “I think launching without a business model is fine, if your costs are low enough.”

A year ago, I would have no problem agreeing with Anderson, especially given the low overhead qualifier. Google launched without a business model — why not? But in an depressed economy where credit is tight, consumers aren’t spending, and job security is threatened, I’m not so sure.

Convince me, dear reader: Is it ever okay to launch a company without a business model?
