Perhaps I didn't make myself clear. When I say it overwhelms the user, I meant that in a positive way. People go on Facebook because it's always updating, it's always giving new information to users. I didn't mean to paint a picture of people ripping their hair out because of the updating stream. I was merely pointing out that the idea of something that is constantly updating is not a good model for education, because students want to feel like they've completed the day's work rather than feeling like they need to go back constantly to finish.
