Well, ss/fixie chains certainly need less lube. But, I am the more maintenance oriented cyclist of the people I know and when I overhaul their chains, geared or fixed, they definitely feel the difference. I should start charging. And a well lubed and clean chain is definitely quieter. My friend's fixie sounded like a mini meat grinder from all the grit. Don't know about squeaks - never heard a bike, besides tires, squeak.
Speaking of which, I've been on the "moderation queue" for cyclingforums.com for a week or two after signing up. They are really slow or I just slipped through the cracks. I don't recall BF having such a hassle. Or maybe they know my goal is to have an account in every bike oriented forum and just be an active member only here...
