All a fair point Lazarus and Ace, but as you say Ace, it's a very fine line to walk with what to say, with a big drop off either side for the unwary.

To play devils advocate - isn't it also inherently wise for an investor in an industry to learn what's needed to be learned in order to form their own independent judgements on what is and is not significant in that industry?

I'd be victim to the first fast talking snake oil salesman out there - and who's fault would that be?
