A simple, searchable online database made up of structured records whose content is generated by the participants. The records normally contain personal information relating to a set of individuals. The database is self-perpetuating in that in order to access it, participants are usually made to submit their own information. Usually incorporates instant messaging capability for connecting participants based on a match.
The purpose of this method is to ‘find’ others with matching needs or take control over your data. For example, matching interests in order to connect or trade. Participants benefit from being able to use a single touch point for identifying matches and are able to compare offers from a pool of potentially similar records. Improves the likelihood of success through pre-vetting.
