How I got feedback from 200 people for just $17

The motivation to visit your website is 17/200 $, so this is a crucial information. You can't use this sample for inference about the real population of readers or customers.

A better approach for those 200 people would be to ask them: i) who do you think would be interested in this site and why. ii) What other services are related to this one. iii) Can you tell a source of clients for this site?

Anyway, a crooked sample doesn't allow a straight thinking or inference. The number of people 200 is not related to the 17$.

As I mention in the blog post, this is not a statistically valid sample. They can, and did, provide me with food for thought nevertheless. That said, your questions are all good suggestions for follow up tests (keep in mind that you need to phrase them in a A/B format).
