I also published my previous Post on a specialist Real Estate Blog a few days ago and as a question on LinkedIn (http://www.linkedin.com)
So far I have not received any feedback on the Real Estate site but LinkedIn has yielded great results in the same amount of time.
Within five minutes of my post I had responses from three people in various parts of the world providing responses with many more following in the next 24 hours until my question dropped out of the top few on the page.
This has told me that LinkedIn can be a very valuable source of instant feedback from a wide variety of people with vast expertise and experience in the relevant area worldwide. This has resulted in my encouraging all of my contacts to use LinkedIn and use it as a research resource not just a directory.
I will publish The Real Estate Gobbledygook Manifesto on here in the future once I have complied all the info I am receiving.
