LOL. It doesn't matter if you have the most awesome product ever invented, if nobody knows you have it, and your homepage is buried on page 17 of the Google results, beneath 42 competitors with similar products.

Marketing is business. And that's tough for me to say, being an engineer by trade. But since launching a startup, I've come to realize the simple, plain, truth... marketing matters. A lot.
