You know, when I initially watched it, I thought that it was cool of Tanner to be such a gracious winner who appeared to be genuinely excited for someone else.  I thought that it was a bit awkward or a little too much, but I certainly didn't think that he was consciously trying to steal Xavier's moment.  We're talking about Tanner Hall...he's always animated and a bit over the top, why did this "incident" demand a 4 page hate thread?
  After hearing Tanner's interview on Jon's blog, I now realize that Tanner sees Bertoni's victory as another opportunity to show the Olympic committee that half pipe skiing is a legitimate international sport, as opposed to it's traditional North American domination.  It is a big step forward for skiing in general, and I think Tanner knows that better than anyone.
