In the efforts to get my husband to join the Twitter world, I have been going over the features of the site along with additions such as Tweetree, Twitpic, and using tinyurl.  I was trying to get him to understand how MUCH I learn from the people I follow, many of which are DEN members.  My district should be including Twitter in their Professional Development because I learn something new EVERY TIME I log in to Twitter.  To you DEN members that have become my Twitter mentors, a HUGE THANK YOU!
