USA digital geostationary satellite?

Excuse my ignorance, but I am confused by the difference between a geosynchronous and geostationary satellite. 

Apparently there are moves afoot to get a high orbit satellite with a footprint over the USA. Oscar 100 does not cover the USA. This one should be digital.  If so, I expect it will get even less attention that Oscar 100, which is seriously under-used.

In my view, these satellites are interesting to access at first, but interest soon wanes later: people know they can access them and then they get bored. It is just like talking on a terrestrial repeater.
