The O'Reilly Radar blog has a link to a video illustrating web 2.0 ideas applied to the real world — with real purchases, folksonomy, tags, popularity, names without vowels (a la Flickr ), free merchandise and other fun.
In a post on Radar they say that the video itself is a guerrilla promo of two Israeli startups: UrbanSeeder (new dating service) and Wishood (lists of gifts and wishes in a frantic blue-pink flickrovskoy scale).
