Regular and real time

Other sites have chosen different ways to change Googles search paradigm. Some have opted for more regular or even real time searching, taking results from the web as they happen rather than relying on an irregularly updated library of results.Daypop (www.daypop.com) trawls news sites and weblogs at least once a day, producing good results, while Technorati.com (www.technorati.com) applies itself purely to weblogs but picks up new pages within minutes of them being published. The basic search is adequate, though it sometimes suffers from time outs. The recently launched tags function incorporates blog categories, social bookmarking site del.icio.us and photo sharing service Flickr to create ad hoc keyword homepages.
