Here's a site I've been working on for over a year now. Actually posted to HN asking for feedback on the idea [1]. So far, it's been a slow road, no over night success or anything, slowly building the site and releasing new episodes as I have time.
Personally, it has been a major growing experience, and showed me the power of the internet. People from all over the world are emailing me out of the blue (and it's not spam!). Almost jaw dropping to think about it. If you have an idea, work on it, release it, refine it, and see where it goes. I had always just sat on my ideas.
Happy to answer any questions, comments, or concerns.
