SolidCoin is a crypto-currency, but the issue is that because it's not decentralized or open-source, it's basically the worst of both worlds. Make no bones about it, Bitcoin is wasteful (think about how much energy is wasted computing Bitcoin hashes), Bitcoin has a sub-optimal inflation curve, and Bitcoin has numerous other flaws.
Bitcoin doesn't have these flaws because some shithead thought they'd make good properties for a currency, it has them because it's a decentralized P2P currency and there's no way to solve these flaws without ruining that aspect. So when you take something like SolidCoin, which possesses all these flaws despite having exactly zero of the redeeming qualities of Bitcoin, well let's just say you'd have to be completely fucking retarded to take two looks at it.
That said, I think SolidCoin discussion is good for BitcoinTalk. It takes those really really fuckin' retarded people and stops them from doing anything with Bitcoin proper. Anyone notice that disregarding a few mini-crashes, Bitcoin's volatility basically fell off a cliff once SolidCoin became a thing?
