Yeah, that's kind of the thing a lot of developers skip. I've done it. When I have an idea, I assume the market exists, and just start driving.

Now, when I have an idea I do an exhaustive search for keywords. I look for any data I can find that will tell me what the market would look like if I could get to the top. Almost every time I've done that, i've realized that there's very little people actually searching for the thneed I was going to build.

I've started to learn more about SEO, and marketing, but there's just SO MUCH I don't know, that I never considered, that having the right guy would help with. They really are an equal founder in my opinion. Building a product no one wants is a worthless activity.
