Launched in 2007 by Dirk Olbertz, a programmer at Cologne, Germany-based Ormigo, NoseRub.com is an open-source protocol designed to create a social network that lives on members' computers, rather than on servers owned by a company.
One place for all your web activity -- and your friends' activity -- with NoseRub.com
Your profile includes all web accounts and any personal information you want to share. People you share your profile with can see the activities you've aggregated there -- for example, the photos you've posted lately -- and can comment on your activities, or mark them as favorites.
How is NoseRub different from FriendFeed?
Unlike FriendFeed, NoseRub is an open-source project. No one owns NoseRub, and as its founders point out, no company can buy it and "bury" it -- a fate that's befallen a number of technology projects and products over the past couple of decades.
NoseRub doesn't live on servers controlled by a single company or group. It's a protocol that each user downloads onto his or her own server, enabling communication between other users while allowing each to guard his or her own information.
Some social networks serve a single purpose or interest, such as sharing photos, sharing videos or communicating with old classmates. NoseRub can unite all these different purposes with a single, open technology.
