For me it's actually that I have too many ideas and none of them are great. What makes ideas great I think is having the right people to try things out with -- hence this tool.
I have the same issue. I have too many ideas with very limited amount of time to work on them. When I meet people, I want to share my ideas and get feedback about what they would find interesting, use, pay for, etc.
I'm building a platform to do this, so I can share my ideas.
So there are a lot of uses for this :)
