Great post! Few thoughts: I am having a similar experience. My co-founder and I have been working on our "this will change the world" venture for the past few months ... we built CollegeJobConnect, a platform designed to revolutionize the undergraduate recruiting system and enable undergraduates to connect with employers. It's a sexy product with a great story. However, due to the summer time period and the "you need to do something different"-ness of the idea, the revenue has been light thus far. Along the way we heard a lot of pain points hiring managers and companies were having, so we built Recruitly (http://recruitly.com http://recruitly.com), a plug-n-play career portal and applicant tracking system allowing you to tap the talent that visits your website. This has been a dream to sell and much easier to monetize. I think it depends what you are out to do: if you are out to make money, you can jump into an existing market and produce a competitive product ("mine is cheaper!", "mine does X better", etc., etc.) and do fine. If you are out to change the world, you have to understand the fight you are in for: you likely will have to change a lot of people's behavior or understanding of how to do something - no easy task. To your point, it pays to do your homework beforehand so you know the extent of the battle that faces you.
