Peter Rip of Leapfrog Ventures has a what I think should become a classic entrepreneur post on business models.  He gives some context about the term (and why it’s often annoying, as in “what’s your business model’ – c’mon – can’t you think of a deeper question?)  He then decomposes the way he thinks about it, ending with a superb chart (that Peter acknowledges it likely incomplete.)  While you might not think about this the same way Peter does, it should stimulate you to “think about how to think about” your business model.
