So what did I learn from this lesson? First, trust your gut. I was using Feedburner and knew it was a very useful service. I felt that others would see that too. They did, but it took some time. Second, I learned that a service can get traction with the little guys and in time, the big guys will come along. I have seen that happen quite a bit since then. And finally, I learned that you can do too much due diligence. It’s important to talk to the market and hear what it is saying. But you have to balance that with other things; the quality of the team, the product, the user experience, etc. You cannot rely alone on due diligence, particularly early on in the development of a company and a market.
