This is unrelated to the larger educational app, but I hope "Startup 3.0" doesn't take off as a name. It's a more fad-based, ephemeral phrase that is being used to mean the same thing as "Lean Startup" (ie the intersection of Customer Development and agile product development)
Yeah we pretty much just put that up there last minute because we couldn't use the term "Lean Startup" (which is a Registered Trademark of Eric Ries). We're talking to Eric about fixing that.
