Flickr, Del.icio.us, Technorati and Furl are four popular services that allow a user to bookmark sites, upload pictures, or mark blog posts with tags. Tagging is a form of organization, like categorizing information, that could become the next big thing and Yahoo could be the one to take it there. TopRank has been tagging for a while now, and we think it is a great idea.
Since Yahoo bought Flickr, one of the major tagging players, they could build their own tag search engine, or merge the idea of tagging into Yahoo search. Tagging is determined by the user, not by search engines, so your search results could be more relevant. If you were to use the Technorati Tag search you’d receive only results that were tagged with your keyword. Not only that, but you’d receive the newest information first.
It’s too soon to tell how or if Yahoo will adopt any of the tagging technology, but they made the first step by buying Flickr.
