Spout is a social network for movie fans. We've seen similar networks built around books, DVDs and music (lib.rario.us, Listal etc), so this is by no means a new idea. Nonetheless, Spout has a few quirks (like those cool tag clouds!) that make it unique. From the site:
We want to fill the gap between what shows up at festivals and what shows up at the multiplex. In that gap is where we're settling a community of film lovers. A place called Spout...Spout sells DVDs. It's our bread and butter. We love going to the local music shop where the guy behind the counter knows what we want. We love finding out about films from a random conversation with somebody else who loves film. We believe the act of buying films and being in a community are connected, not two separate things. We hope you agree.
