Social networking is something most of us use to share ideas, media and to chat, but it’s not very private. Now you can setup and manage private groups with a new iOS app called Glassboard.

[ad#Google Adsense 300×250 in story]Developed by Sepia Labs — NetNewsWire founder, Brent Simmons’ new company — Glassboard was designed to be “private group sharing done right.” The company says that if you start a group, it is completely private — there is no way for anyone to search for a group or a person in a group, so the only people that know the group exists are the people in it.

“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,” wrote Sepia Labs. “Your dog pics will only be seen be the people in dog pics, and talk about classic cars will only be shared with the classic cars board members.”

Only the leader of a group can invite people to join, so you don’t have to worry about people showing up out of nowhere.

Glassboard is available from the App Store and is a free download. You can find out more info about the app and service from the company’s Web site.
