Man - I've been away from Slashdot too long. I forgot how intelligent the conversations here can be. No really!
The honest truth is that I have no clue whether it's happening or not, but it is refreshing to hear it debated based on data and math. So much of this conversation gets framed around "You're an idiot to believe that" or "You're a fool to deny it" rather than "The evidence seems to be pointing toward something, but we're still trying to figure out what".
