For each new piece of information you track, there is an equally old and useless piece of information you must throw away. If you continue to follow new people [on Twitter], eventually they’re going to overwhelm you with their casual information flood, so you must get in the habit of removing a person for each new person that you follow. Incidentally, the first law tastes great with RSS feeds as well.
