Yes, but that's not saying much. Namecoin is more successful in my opinion, depending on how success is measured (not price).
I'm all for competition I suppose, but litecoin is certainly not that. It's a gimmick fork.
So far we've seen more than half a dozen alt-chains, which one is not considered gimmick? none?
Namecoin is less of a gimmick than the others. But, yeah pretty much.
