Show HN: Brainpick.co.uk – Earn money by answering StackOverflow questions

Hi! I am looking for honest feedback on my next product. Brainpick.co.uk is a Chrome extension that adds a button on StackOverflow standard page to pay for an answer. You answer and get paid when the answer is accepted. I am selling it to Enterprises as an affordable, subscription-based, pay-as-you-go service. Let me know your thoughts.
