Its not directly the answer of the question but relevant. I believe unaddressed/overlooked problems are the greatest origin of a potential startups but not what we think an legitimate idea, actually is. For the 1st time every idea seems awesome, take time revisit after a few days, you will wonder that most of the sparks are gone by now. If it still looks promising start doing your research. This is another eliminator of an unique idea. Though it doesn't have to be unique. But you should bring your own flavor into it.
