I think you guys are seriously underestimating what the power of familiarity can produce.
In my opinion, the advantage of bitcoin is it being the "first" mover in becoming a mainstream crypto-currency.
I also think the name in itself is extremely powerful. It sound simple, yet invokes a sort of cyber future image.
Litecoin and Feathercoin just sound weak in comparison. (Phonetically weak)
I think we will soon start to see threads about how much is 'insert crypto currency' in BTC instead of how much fiat is BTC worth.
