As it was mentioned MVP management depends significantly on public opinion, so customer validation process is very important. Do not neglect testing your hypotheses with actual customers. You can conduct early customer interview in various ways: in person, by blog, by email, etc, but try to be flexible to the customer's schedule.
As for the questions to ask, try to make them open-ended, shot and unbiased. Let them talk, but be prepared to hear what you don't want to hear. Remember, the goal is an early stage learning, not a sale. The same goal can be reached applying blogs as validator of your product MVP viability. Blogging platforms with the correct approach can provide support or disapproval of new founder's ideas from a community of followers.
