Thinglink ( http://thinglink.com http://thinglink.com ) has tried several approaches in this space. Originally they offered this very abstract kind of "URL for things" service, then they pivoted to be more a social network around things, then they pivoted to be a social network for designers and people who like designer clothes and other designer objects.

It's still operating in a same space "to URLify real world objects", but it offers an immediately useful service, for example for fashion bloggers.
