Various example embodiments relate to a mechanism for writing feedback to a personal repository accessible to a personal computing device. The mechanism may receive a request for writing feedback of a user of the personal computing device regarding a particular item to the personal repository. The mechanism may also store the feedback of the user regarding the particular item in the personal repository. In addition, the mechanism may send a response to an incoming query from a personal computing device controlled by a peer of the user regarding the feedback of the user stored in the personal repository. In some embodiments, feedback contained in the response to the peer may be constrained by repository access permissions specified for the peer by the user of the personal computing device.
