I think it could be cool to have some more coins or other bitcoin-like commodities in the pool. But I just wish the bitcoin clones would have some real purpose and novel features. Well, maybe I'm mixing up purpose and profitability?
Any thoughts, everyone? Devcoin? Litecoin? Others?
I wasn't making any comment on the usefulness of devcoin, I just don't see a reason not to merge mine and sell the devcoins for a tiny bit of extra profit.
In terms of purpose, Litecoin looks to be the best of the alt chains, but it can't be merge-mined with Bitcoin.
