The Twitter feed project is going well. We spend some fruitful time at the beginning of each class going over some Tweets and the students, this quarter, are compiling their tweets into a portfolio for submission at the end of the quarter.
I was explaining the project to my colleague and he found this article that investigated and ultimately determined how to say Twitter in Latin. (Hint: Catullus 3 is involved.) I particularly liked seeing the Latin version in the Twitter font.
