I know it's still new but Gridcoin may have a good future.
Normally we'd add it to the vote, but currently I don't see it at least on Cryptsy, so it would be hard to add it without a market. Sorry. Maybe next vote.
Don't forget to consider Nextcoin - NXT.
Same with NXT, only see it on one exchange, might have to wait for it to get on more. Prices would be too volatile if coming from only one market.
Apologies for any inconveniences.
