This chapter analyses the world of user-generated content (UGC) and consider what is actually happening in terms of contribution and richness of content when young people take to this format to share their creative activity, and how the processes of commenting and review can contribute to the development of skills and knowledge. The advent of Web 2.0 where everyone has potential to become an author as well as a reader of multimedia texts- enabled anyone with an internet connection to share products and creative acts with an audience. Wider research has found, as we did with the British Broadcasting Company (BBC) Blast, that much of content of message board dialogues is trivial in terms of analysis or comment, rarely going beyond simple statements expressing admiration or possibly asking how the work was achieved and what tools were used. These components of learning dialogues also resonate with Laurillard's work, which suggests that a learning dialogue includes discussion, interaction, adaption and reflection.
