Instead of just copying what quark and other coins have done, I think there should be long term strategic change in the hashing mechanism to make it truly ASIC and bot-net resistant.
We can't just keep hardforking Litecoin again in the future when people start building ASICS for X11.
what did quark "just" copy, if there is copying involved it would be better to say that it got copied tons of times? and by other coins you mean litecoin too right?
