BooksWeLike is built on Andy's XML-based content management system, Thingster. It is underpinned by a belief in the power of social content engines, signalling and constituency marketing, and the long tail. many2many ^

Thingster is an open-source weblogging service for locative media. It is being developed by Anselm Hook, Tom Longson and Brad Degraf in association with Locative - a multi-disciplinary group of theorists, artists and engineers exploring the implications of attaching information to place.
Users can publish 'virtual post it notes' about any geographic location: a street intersection, a street address, a restaurant, a hiking trail or a geocache.
The reward or 'exit strategy' for a project like Thingster is social and environmental. The hope is to enrich neighborhoods such that it becomes easy to discover local services at a lower cost and to create additional environmental awareness.
