Through 1000tags.com, foreigners have introduced a new professional Tags business service: ZoomTags. ZoomTags provides an API interface, so website owners or bloggers can place commercial Tag clouds on their web pages via this API. When a visitor clicks on a Tag, the page redirects to an advertising-matched result, much like Google's AdSense. Would Yahoo and Google take such actions? It's hard to say. (diglog.com)
