It's probably just me... but why do so many protest websites of this nature look so bad and shoddy? Sure, it's not the appearance but the content that we should be taking into account, but I'm sorry - no matter how well researched and documented their objections might be, making it look and feel like so many other conspiracy websites 'proving' that moon landings were fake or UFOs built the pyramids has undermined their cause. Unless that is their target audience?
Don't get me wrong - I'm not a great fan of the powerline stuff, more because it is fairly flaky than because it is 'the worst thing to happen to Shortwave radio ever!'. I am using it in one library out of necessity, where I can't run new cable as it is a listed building (which in this environment would have required spending a number of months getting approval from various internal and external committees). I do know of someone (anonymous in case she's involved in that website) who was very vocal against the first generation 11mbps stuff who had personally run various tests to demonstrate the problem (don't know about the subsequent versions). But that site just makes me laugh at how bad it is and devalues anything it might legitimately have to say. Which might be a shame.
