I don't know, it seems to me as if it's re-animated people's pain in some ways... I think people are relieved that he was "clean," and yes, in some way the idea that it was possibly murder rather than suicide makes people feel less--angry? At him?
The Sweet Addy board does tend to get a bit vitriolic at times, like most Internet forums--still, I think it's a nicer place than most, just ripped up because the artist around which it's centered has died. And Elliott Smith may be treated like a "god" there, to some extent, but I wonder how we would've treated Charlie Parker, had we been alive in 1948 with an Internet board. Clearly many people accorded Parker that reception, as they later did Coltrane... I would not say that jazz fandom has been immune from this particular kind of response by any means--and that Smith, for the so-called "emo" movement in music, was a kind of Parker figure as well.
