One of my pictures went into the Schmap guides, under Borough market, in their market section: very difficult to navigate to but a good read nevertheless :-)
Aggregating internet users contribution and "rich media" content into "social city guides" is interesting but often failing in its execution. The idea is to aggregate content, just like Wikipedia, for richer guides with more up to date tips.
Zagat does this already for restaurants (subscription required), and Tripadvisor for hotels and holidays but in practice there are many small players and in the current context many may go out of business as VC funding runs out. In the meantime, check out TrustedPlaces.
