Perhaps "hippies" have the vision to create something that will change the world (a bold claim about twitter... but at least somewhat true already) and "non-hippies" have the pragmatism to make a copycat mmorpg that will rake in a few million bucks but no one will remember next year.
When I think about what spurred the creation of a memorable technology that changed the course of human history, I see vision, not monetization. (Ford => a car for each family, Edison => light in every home, Apple => easy to use computers, Google => bigger, better search)
