In fact, I didn't hear of _why
until he disappeared, and @jresig made his testimonial to him. Now retrospectively, I admire his creativity and humor... including an appreciation for his virtual "death", if it was meant to be a part of his overall character.
That said, I appreciate that people have made all of his works available online, and those projects stand on their own merits. I don't find much value in celebrating _why himself, since that's his personal project, not ours.
