As part of my iTunes U research, I set up a TwapperKeeper to capture all tweets using the word itunesu. Would you like to have a look and see what people are saying? Go to:
You may need to adjust how many responses are displayed per page.
I have done some analysis of these tweets, but am still mired in the process. For my ALT-C presentation on iTunes U as the Corporate Channel of Free Learning Resources, I was able to divide out all languages used to tweet about iTunes U in a several-week period late summer-early autumn 2011. I also detected the main themes and some unexpected themes of said tweets. You can look at my ALT-C presentation on Slideshare.
