You.
There's thousands of other coins. And just saying one of them is rubbish.
I do admit there is innovation in other coins, neat things like a distributed DNS or power savings (PoS).
But those things aren't particularly useful at the moment, at least not enough for people to start using the coin.
In the privacy area, there seems to be only a few horses in the race.
>Bytecoin
>Anoncoin
>Darkcoin
>Zerocash
Bytecoin uses Cryptonote, Anoncoin claims to be implementing Zerocoin Lib, Darkcoin has Darksend and soon Cryptonote ring signatures (might want to clarify this with the devs), Zerocash is a coin that researchers aren't really making yet, for one reason or another.
blah blah you've heard it all before, Darkcoin is a winner in the privacy crypto-currency industry so far, winning "stock" in the winning industry type of thing
