I do fear a duplication of effort in the digital currency movement. It could get to be like linux where it goes from genuine freedom and competition to outright fragmentation. For those of us who believe in the politics of digital currencies this is a little bit concerning because it takes resources away from the more viable currencies. Endless forking and fragmentation has not helped linux compete with the establishment and I fear that the same may be true of digital cryptocurrencies.
For people who are only interested in speculation I suppose that they are interesting and I also suppose that nobody forces anybody to get involved with them.
Just my thoughts.
I say people should keep on creating new currencies, until one actually does have a good hold. You never know what might happen. It could even be a catchy name that changes the whole game.
The name is what gets it out there, usually regardless of it's features. That and if it was pre-mined or not.
