I was an early Twitter user and I always used the website feed.  Once I started following more than 1,000 others, my feed became unmanageable...until I revisited Tweetdeck.  Now I sort my tweets into lists that are relevant, sorted and timely.  All of the sudden, Twitter is fun again.  Moreover, Twitter remains THE BEST source of professional development.

Need an 8 minute tutorial on how and why to use Twitter as an educator?  Check out the video in this post.
