One of the good ideas:
Real-time services like Twitter and FriendFeed illustrate the potential usefulness of a streaming interface. I don’t have to see all the tweets in my stream; if something is specifically important it will be re-tweeted by people in my network. The more this happens, the better the chance that I will eventually see it. What if we made e-mail into a stream? If a message is important, people can re-mail it, and it then moves back to the top of the list.
