Visual design as decoration is probably less effective, and I think you'll get a lot of that with "Unprofessional" designers. Visual design as a way to amplify/enhance existing well-designed interactions is definitely effective (i.e. strong button affordance, good use of color to convey meaning, etc). This is the type of output you'll get with a "Professional" designer.
Philosophy aside, I think you'd probably do better with qualitative testing. Do people tend to complete tasks easier if the action being tested "looks" easier? Does the brand identity match the audience you're targeting? Are your design patterns consistent across the site? Etc, etc. It's certainly a bit more nebulous but I think with the right questions you could certainly use A/B testing to answer some of these things.
As far as sharing ideas go, I tend to only share with people I know. I violently agree that collecting feedback on an idea is immensely valuable, but there are many ways to go about doing so. Posting them into Hacker News is probably the last thing I'd do, for two reasons:
1) Unless I'm building a super niche product targeted at developers/entrepreneurs/designers, then Hacker News is not the place I should be collecting feedback.
2) If anywhere there exists a capable group of "idea executers", it's here. Paranoid? Maybe, but unless I am going to gain extremely relevant/targeting feedback from my core audience (see #1), why take the risk?
