Last summer I discovered Openbook.social on Kickstarter and I decided to backe it. I stopped using FaceBook long ago, as most of my friends. I was bothered by the constant notifications to others about anything I did, any comment I made, on photos or communities. Ok being social, but this is too much. OpenBook also has a different business model, not based on exploiting personal information, but paying for optional Premium services. Its source code is also open. I hope dearly it succeeds.
