Social sites like Facebook and Twitter let us reach out to all our friends at once. If we have something to say, a simple status update, tweet or post conveys the message to all of them in one fell swoop. This immediacy is the common denominator of social services. And now, Keepio aims to take it one notch above.
Keepio is a site that lets you create a catalogue listing all the items that you have in your possession, and once you have done such a thing you are empowered to sell and/or swap any item that you have catalogued with your whole social graph.
Also, users of Keepio are enabled to write (and share) reviews of all the items that they have, be them new or old. The idea is to give their catalogued collections a further degree of contextualization. If someone wants to sell off any of his items, he can write a review explaining what makes it special and why buying it would be a sound transaction.
