Greetings from Breckenridge, Colorado!  It's amazing how one can travel and with an iPhone and laptop in hand, not miss a beat whether in the Rocky Mountains or Mauna Kea on the big island of Hawaii!  Have you heard about the Twitter phehonomenon?  Upon my re-entry to warmer climates, I attended the Web 2.0 Conference in San Francisco and learned how "twittering" is taking the business community by storm.  There are many practical uses for twittering.  The most useful I found to be was for conducting on-line research.  Set up an account for free, conduct searches on various topics of interest for your business or social needs, and find out who is "twittering" about that topic.  You can also see which topics are being twittered the most and make direct connection with thought leaders in your area of interest. Check out www.twitter.com and start experimenting with the latest on-line marketing tool for business.
