Great article! I've encountered some of the same insights as I embarked on my journey to find the nearest competition for my idea. Many are close, but none on point. Finding competition definitely makes you refine your approach and your differentiator. In hindsight, it is probably the best thing that has happened to me thusfar.

To sdizdars point, your customers absolutely define who is the competition.

So glad for having read "Differentiate or Die!" by Trout in college to know the necessity of that great differentiator.
