It didn't happen to digitalcoin.
Digital Coin is an attempt to save the system by changing philosophy. It's not a bad idea, but it depends on a larger "experts only" attitude.
Feathercoin is too similar to Litecoin to ever be very successful. It's always going to stand in Litecoin's shadow... and even if Feathercoin does successfully innovate, Litecoin can just apply the same idea with it's superior devs and community support.
Cognitive dissonance level: AZN.
FeatherCoin successfully innovates.
But Litecoin has superior community and developers.
Please enlighten me how litecoin has superior backing if FeatherCoin successfully innovates. I'd really love to understand this rhetoric. This is the kind of logic that kept Conan O'Brain from getting the Tonight Show. Yes, I went there.
Feathercoin going on mtgox is also a pipedream. There is no hope in hell mtgox would start trading a coin which was successfully 51% attacked recently, it would be a PR disaster if feathercoin got 51% attacked whilst mtgox was trading them and it would cost them dearly. Maybe it would happen one day, years from now... but I would bet within a year it's value is under 1 cent a coin.
This is just absurd. 51% isn't magical. It takes both infernal rage and opportunity to 51%. The infernal rage has already turned inward.
