Technorati’s homepage has the quote “50 million blogs…some of them have to be good.”  (Matt).  Weeding out the useless from the golden nuggets seems an undaunting challenge.  Tagging may be a useful tool for finding individuals with similar quests, with the same passions, or with new creative viewpoints.  http://librarytails.pbwiki.com/ is a wiki with some great links to help librarians share ideas.  Check out the section on tagging.
