I am a big fan of Dennis Kennedy and his blog.  I personally had the pleasure of meeting Dennis at the American Bar Association Tech Show in April of 2006.  Dennis gave several presentations about different aspects of technology including advice about how to set up a blog and a podcast.  He really turned me on to really cool idea.  Anyway, Dennis is also admired by the the publishers of X1, a desktop search software utility.  They have given Dennis 50 free licenses to give away to his readers.  Once they are gone, thats it.  You will have to purchase a license.  If Dennis recommends it, it must be good.  Check it out and become a subscriber to Dennis’ blog, too.
