Hitting the Sweet Spot in Innovation

This post on techdirt highlights an interesting concept that just having an idea alone isn't enough to make a product valuable. Mike Masnick explains that a lot of experimentation has been done on products in order to hit that sweet spot, and this dates back to early inventions. Tweaks and minor improvements to ideas is a great way to see what works and what doesn't work in a market, but with our patent system that might be a little more difficult.
