I think there is an elephant in the room here. (Sorry if this stings anyone)

The collective We have been led to believe that we must make something original to be great. Don't make another social network, too tough. Don't do what Instagram did, it's too (pick your reason) risky / saturated / lucky / etc.

The thing is, entrepreneurs have no reason not to shoot for the moon, recreate everything. Why do we resist? The big name funds probably won't invest for fear of cannibalizing their current holdings. Think about that next time you hear a VC or read their commentary (or any commentary for that matter).
