Don't underestimate the disdain that TA devotees feel towards anything not based on traditional stock/commodity-market technical analysis.
The very idea that news might affect a market (even as new and unprecedented a market as BTC) is heresy, an affront to their existing orthodoxy.
Nope, I believe news affect FX markets, but not bitcoin.
As for news not affecting Bitcoin, how about the news of the Satoshi Dice sale and payment to shareholders in BTC? Almost immediately the price dropped by over $10 and while the expected great selloff never happened, it took a week to recover. I'd say that news affected the Bitcoin market, albeit only temporarily.
It wasn't almost immediately... it was 6 hours later after pages of discussion on where cheerleaders made up bullshit reasons why it would drop. Once they had enough people convinced, it happened. It is not the news per se... it is speculators overreacting to news and whipping to forums into a panic. The news didn't change fundamentals and the market made that clear by burning most of the idiots who sold off.
