Tagging…can cut through the online clutter to deliver more relevant bits of information. That is because many versions allow users to search only sites that other people have already deemed useful. It also makes it easier to find desired information again. Users says tagging services can simplify online endeavors like shopping for a new road bike or acoustic guitar because they allow a prospective buyer to quickly access saved information.
While tech-heads have been using the method for the past year or so, tagging is now moving into the mainstream. Silicon Valley heavyweights — along with a number of new upstarts — are now putting major resources into developing tagging services. Last month, Yahoo Inc. bought the popular tagging site Del.icio.us (pronounced “delicious”). Now, the Sunnyvale, Calif., company says it plans to allow Del.icio.us users to access their tagged links through My Web 2.0, Yahoo’s own tagging site.
One new site, Shadows.com, allows individuals to save their favorite Web sites under keywords that others can also search. The site, launched last October by the co-founders of Pluck Corp., based in Austin, Texas, attracts more than 275,000 unique monthly visitors, according to comScore Networks. Last week, iLor LLC of Lexington, Ky., launched PreFound.com. Like other bookmarking sites, it allows its users to upload pages they want to save into their own profiles or share them with the public.
