The primary use is for receiving our data broadcast in places that have limite/no/costly connectivity. We want to provide a basic information service that's available everywhere. Right now there is an audio stream coming down (Voice of America; it's free content), news feeds, weather updates, and the day's popular Wikipedia articles. It's a 10kbs datacast.

We also act as a relay for ham packet radio (APRS). Hams can send messages that eventually get picked up by internet-connected gateways. We take APRS messages tagged with OTHER and broadcast then over the two satellite beams.
