this is why i made <a href="http://goingtorain.com" rel="nofollow">http://goingtorain.com</a> years ago because i rarely care what the exact temperature is going to be, just whether it's going to rain.<p>similarly, i made a clock called pixelclock (<a href="http://jcs.org/notaweblog/2005/06/28/pixelclock/" rel="nofollow">http://jcs.org/notaweblog/2005/06/28/pixelclock/</a>) because all i cared about at work was whether it was time for lunch or time to go home.<p>sometimes things are better left vague.
