In this paper we introduce our experiences in applying the Web 2.0 philosophy to build a TV guide system for Interactive Digital TV (IDTV) platforms. Subscribers give their opinion about TV content and, informally, a folksonomy is progressively built. Based on this shared knowledge, the TV guide obtains personal recommendations and allows users to browse among the multimedia content. Additionally, and over this collaborative layer, a more formal vision enables applying semantic reasoning to supplement the knowledge informally inferred.
