Glassboard is an app for sharing privately with groups. Think Facebook but private, and focused around groups. In Glassboard, you create ‘boards’ which are groups of people around a common interest, and you can share messages, comments, photos, videos, and even your location (when appropriate).

Think of each board as a silo. If you have a board that shares dog pictures, and a board that talks about classic cars, neither group will ever know about the other. Your dog pics will only be seen by the people in dog pics, and talk about classic cars will only be shared with the classic cars board members.
