I'm working on a brainstorming/idea generation site as a side-project. No idea if people would want this.

Which lead me to down the path of wondering if there are any idea pitching sites. In the meanwhile, I just created a subreddit(/r/ideaspitch) which could serve that function for the time being, just so that I can relax and focus on my original idea again...

So yes, brainstorming/idea generating tool.
