Pop! is an app that let's you decide how far you go with your content locally.
Pop! allows you to put a ring on a map at any size, from a few meters to 20 miles wide.
If you go to an event of any kind, and want to chat with people around you, you can simply make a ring and meet new people. If you want to notify your neighborhood of something, you can make a ring to notify.
If you want to inform your city of something, just make a massive ring. If you want to notify your campsite of something, just make a smaller ring.
If you are a business or musician wanting to promote a grand opening or concert, you can cast a massive ring and center it over the downtown area.
Users can only see your notification or chatroom if they are within its bounds. If they leave your area, your ring gets removed from their feed.
The very fact that the area can be customized allows your location to be masked to a general area, so nobody will know exactly where you are. So swivel and scale it however you'd like!
All pops are subject to votes and have a one hour duration. But if you want a sustained interaction with somebody, just click on their picture and send a bump their way! Just keep in mind that they'll be able to see your latest tweet.
