John Battelle points to Brian Dear, who imagines a search engine where user-generates tags are searchable: “…if more and more services in 2005 add user-generated tagging, will ‘federated tagging’ be far behind? And if someone were to index all the tags from these various sites…. would the result be Taggle? Imagine: a service where you type in a keyword, and you get back all the hits that have that word as a tag. If Flickr, del.icio.us, and umpteen other sites cooperated, then an uber-tag-search service might just work.”
