I don't think that establishing a Linux Society credit card is a revolution. It's a me too project, especially, when compared to the pioneering work of Bank of America in the 50-s. I would even guess that Linux Society credit card is not doing that well: another niche financial product to serve fiscal conformists among techno non-conformists.
One of the real revolutions actually happened today: Apple announced that they will open APIs for their iPhone. This is big because it creates a whole new application space. Not a great invention, but a very significant innovation.

Cheers!
