I like the following post because it gives you some great examples of how Twitter is being used by many non-profits. As a baby boomer I thrive of experiance-based technology applications. Ok, what I mean is show me someone who is using it and then I believe you.
So, in my continuing look into many of the practical applications of Twitter I was happy to see this post by a social media expert.
Also, I appreciate this great overview of Twitter by another social media expert.
