Your missing so many alt coins.
No doubt. Some of these coins mentioned are "dying" coins that are not supported by active mining any longer, or are not traded on the exchanges yet (Pheonix coin). Feel free to post a more comprehensive poll if you really think there is a chance that those coins would skew the results

Poll results are now showing Litecoin by a landslide. The others are not really distinguishable in results:
Ripple (no 2 by a couple votes).
Which coin would I
like to succeed?
PPCoin. I know there are a lot of LiteCoin fans, but I love PPCoin for its novel approaches in several respects - mining, max number of coins, and built-in inflation. I think it truly has the capability to proceed as a legitimate (and STABLE) currency.
Which coin do I think
will succeed?
Ripple. Big money will win the day, but not if these guys can't make it truly distributed. They've got to pay attention to the criticisms placed on their current architecture and create something smooth and workable. If they can do that, it will succeed definitely.
Keep voting, unwashed masses!
