We created a startup Yardale in 2010. It was focused on bartering. Basic idea was that you create 2 list, wants & haves. You can share your profile on Facebook and and hopefully your friends will see what you want to sell or barter. It had automatic matches if 2 people have exactly an item that they want to exchange. It failed because lack of some essential functionality like automatic emails, automatic matching with items of same values, etc. Also marketing efforts didn't workout and we had only our friends and family sign up.
