Quark is going to be huge: It is incredibly fast and it is the most secure coin there is, at a time when the security of cryptocoins is becoming a major issue, and transaction speed will become an issue for any coin that wants to move beyond enthusiasts and into the mainstream.
Fast doesn't really mean anything, you have to wait for more confirmations anyway to ensure a secure transaction. More confirmations = more time. It's a zero-sum game. Darkcoin has 11 rounds of different hashing so you could argue that that is the most secure, not quark. You're trying really hard to get people interested, but the fact remains that it's mined out. No one wants to mine a mined out coin, and no one wants to buy off bagholders.
