What I want are separate feeds for "firehose" and "friends". My friends have better things to do than to post to Twitter 20 times per day. A bunch of firehose feeds (NYTimes news updates, for example) or Twitter celebrities (Nicole Cliffe) will make it impossible to see the signal. A simple UI change (a "I don't plan to make any more tweets for 4 hours" button) should make this filtering trivial to accomplish.
