It was only a matter of time until Twitter feeds found their way into academic writing which like other new media artifacts that came before it (emails, websites, etc.) begs the question, how to cite, how to cite? Amit Agarwal in his excellent blog, Digital Inspiration, has a nice little post on how to do just that, The Proper Way to Cite Tweets in your Paper.
You might want to consider adding Digital Inspiration to your blog feed. It's an award winning technology blog whose goal is to "help you take maximum advantage of the software tools and web technologies at your disposal so that you spend more time doing things your really love."
I like getting the weekly Newsletter in my email.
