I wrote a blog post related to this yesterday. I agree with the author 100%. I can't remember how many times some business guy tried to pitch me on some stupid idea without an inkling of knowledge about programming or how the web works. The worst part is that they generally have no money either. If you have a good idea with some idea of how to implement it and a clear vision, you may be able to sell me. If you have a half-assed idea and are just trying to jump on the internet millions bandwagon because you think it doesn't involve real work, go to hell.
Could you update your profile with contact information (the email address field is not public). I'd love to read the post you described. It sounds like I've recently came to the exact same conclusion, except I'm actually the business guy who used to pitch stupid ideas (ah the naivety).
Thanks, a rant indeed. I remember seeing this blog posted somewhere a few days ago, best of luck! I can definitely relate to your "F* it, I'm just going to do it" attitude.
