Sneek Peek allows you to share and view photos in your area, and it is a great way to find out what is happening right now! When you share a photo, you can specify its reach, but your friends will be able to see them unhindered by distance. Your most recent photo is the only visible one, so let people know what you are up to right now!
Sneek Peek is a good way to keep up with your friends, and why not follow someone if you are not quite ready to call them friends yet. Following a user also gives you the opportunity to see whats up, regardless of their geographic location.
