My take (for what it's worth)... If you truly wanted to get "a feel" for what people may or may not buy and/or how much they would pay for an item, I would have recommended that you write the post in the form of a "poll" or multiple "polls"... that way you would stay clear of any "personal attacks" or whatever, and get some hard data that could help you better understand the market and how it is developing or not-developing... you could get real intricate as well, and direct the people to a complex poll where you could get all sorts of data, like how demographics play into it, in many forms... be that location, age, income range, mental stability (j/k - had to throw that in), etc.... you get the drift, I am sure.... I think you could have some fun with it, as well as it would be interesting to see the results (at least for me, I love data, marketing, etc.)

Best of luck.
