Thanks for suggesting it, I didn't know about that place. It seems like a flood of unrefined ideas coming from non technical people. I also see a lot of "that would be a good business" type of ideas which is definitely not what I'm after.

The good thing about that place is that it points out some obvious flaws with my initial idea. Maybe doing it on Github instead of reddit and focusing on developers and requiring a bit more details before submitting a suggestion would solve these? I don't know.
