PC Magazine has published a list  of “picks for the top new or under-the-radar  sites of 2007.”  Some are just for fun and others offer valuable information.  The web sites named cover topics on health, reference, entertainment, music, news, reading and more.  To find PC magazines’s list go to http://www.pcmag.com, scroll to RECENT STORIES at the bottom of the page and click on the link for “Top 100 Undiscovered Web sites.”  (One of my favorites :  http://www.verbotomy.com )
