Dear Jonwit, I would stop at some point and would not consider yelp, tripadvisor and google places as Deep Digital enough, as these are mostly POI for tourists. For me Deep Digital is a kind of “Knowledge Repositary” where people may get a profound knowledge about the places, not just advice on the best pizza in the town. “Educational” is the key word here. Therefore I would stick to the list of: - map (with turn-by-turn guidance) (for orientation on the site and preparation at home) - wikipedia (for in depth learning at home) - youtube (for fast and educational learning at home) - izi.TRAVEL (for educational learning on the site with an auido guide)

I would also make efforts in bringing it up to the OSM help center. But I am still young in this system (just 1 day), so I will learn it first.

I liked the idea very much. May I suggest you add one more layer: the guided tour audio-photo-etc files thru the audio guide platform izi.TRAVEL. It is like youtube, but for those who are on the site. it will help visitors to get the right story played in the right place on their mobile phone, GPS-triggered. It works online/offline and supports any language and any phone OS. I can help if needed. Write to alex@tourski.com
