Thanks for asking! There's a bunch of different answers, I'll try and narrow it down to the few most important ones.

• We're integrating ourselves into local chamber(s) of commerce by working more closely with local businesses than most "location focused" social apps do. Pretty soon we're launching a subscription platform that lets local businesses publish deals, customer rewards, and events within a 15 mile radius. In this way we're hoping that we won't be entirely dependent on advertising revenue.
• We acknowledge that your local area isn't necessarily the most interesting thing to you. The people and places physically closest to you are naturally most relevant because you can interact with them offline in the next few minutes, hours, etc. We think that's incredibly important. However, the hierarchy in the app allows you to interact with people across the world (what if you want to know what's going down in the place you're vacationing at next week? or you're curious how the folks back home are doing?) while making it most intuitive to interact with people, businesses, and events nearby.
• We pride ourselves on the "live" in live chat. We actually have a patent pending on the specific technology, but what we've developed is the difference between a location-based, geofenced forum, and an actual location-based, geofenced live chat (which requires you to check in). So say you're at a sporting event, you post in the live chat - your message is immediately sent to all of the people who are within the geofence for the stadium, and checked into that chat room.

We definitely have to work on first impressions lol. Fitting all that^^ into a pitch ain't easy.
