Did any of that mean anything at all? Was Dave on medication? Was this code to let us know he was being held against his will, and we all failed him so he's actually been dead since 2010? We'll probably never know. Or maybe this will clue us in:
Thirty-one people saw Dave Matthews saying, "Hello," and thought,
"Oh, hahaha, that is priceless. Oh my God. Gotta let the world know."
That was definitely code for something, but more than likely it was a message to the guy who supplies Dave with mescaline and canned air, rather than for fans or authorities. His final posting in 2010 was just a link to this video that depicts what happens when animation software falls into the hands of people who know what gasoline tastes like.
