Bitcoin was only the beginning
Ethereum is bitcoin style disruption (blockchain technology) that is generic across anything writable in software. That's huge.
Etherum is not ripe. It's not something you want to devote a lot of resources to but it is something you want to keep your eyes on to monitor because any successful etherum software can disrupt any field of endeavor as bitcoin is disrupting banking. Look to hear about ethereum in a mainstream news outlet near you in mid 2015.
