This is way better than polling based on false pretenses as suggested in previous submissions. That is a great way to solicit feedback. Thanks for the submission.
Could you explain what you mean by this? The writer of the blog didn't publish her questionnaire or responses so there's a question in my mind of how effective it was.
Where? All I see is this: "gave a brief description of what the website/service offering would be then." It seems like a key part of the survey is missing along with detailed responses.
I use mturk a lot at the startup I work for and while I think it is an amazingly powerful tool, one thing to keep in mind for experiments like yours is the number of actual unique worker Ids.
For example those 200 responses, I hope you really mean you Looked at the actual number of unique people who accepted hits and thus you actually published a (large) multiple of that 200.
In my experience if you send out 1000 hits, about 70 people will all of them.
There's no way to easily filter so that a worker can only do one hit without some API/iframe trickery.
What about the "Number of assignments per HIT" field? It says "How many unique workers do you want to work on each HIT?", it sounds to be what is needed here...
I just tried it and the workers were, indeed, unique. However, it seems that the feedback was somewhat of low quality, as, for the "would you use it?" question, almost everyone (understandably) said yes (why not, really?). Those who answered no cited privacy concerns, but nothing integral.
For the "why would you use it?" question, they mostly repeated the use case I stated above. This was only 10 people, as I wanted to test it out first, but there's my data point for you.
Validation is not validation unless money and pricing is brought up. I don't think she mentioned pricing anywhere in her surveys. I would "use" anything. Paying for something, on the other hand, would have put me in a completely different state of mind.
I'd go further: many people will happily agree to buy something for $x when they think it's all hypothetical, but would never actually buy it. Hence the oft-repeated advice "don't ask people if they would buy, ask them to buy".
I'm not sure what the writer meant by segmentation, but for what it's worth, based on what I've seen mturk workers aren't really equally distributed across the world. From my own observation, a large majority of the workers are in India.
How biased is the survey likely to be? Now, it is hard to take a few hundred sample size and be unbiased by any measure. Given that, I wonder what specific kind of bias does posting a survey on mturk throws up, since the survey takers are actually "working".

Just some food for thought.
