del.icio.us: "The question everyone asks is 'what is the business model'.  To be completely and totally honest, we don't yet know.  This was a seed investment and none of the investors put up very much capital.  Joshua retained complete control of the service and is going to focus on making it better.  That is all anyone wants to see happen right now.  In time it will become clear what the business model should be.  And there are a number of them to choose from for sure." —Fred Wilson (Union Square Ventures)
