<p>Well… I’d say that it’s a bad idea based on conventional wisdom, but I had a friend who sent in a rather long supplement (including a poem he wrote in spanish) and he got in. I hesitate to say he didn’t have much special about him, ‘cause he was a freakin’ genius, but his major extracurricular activity was football, and he definitely wasn’t passionate about it. His real passion was philosophy (and he’s a philosophy major now, who writes on philosophy for the Yale Daily News) and I think the writing sample helped substantiate that. He got in.</p>
<p>So… I suppose you should consider sending it if it really says something about you that isn’t revealed anywhere else on your app, but otherwise don’t bother.</p>
