Obscure title yes but it'll do for right now.
Often we go through life wanting to do a lot of things: we want to be successful in school and our careers, we want to have a loving family, we want to maintain our health and exercise, we want to give back to our communities/religion, etc. But rarely do we have time for all of them on a consistent basis. All along, we also have a lot of ideas of different ways we think the world can improve but again lack time and the resources to fulfill the execution needed to bring said ideas to life.
Sometimes we tell these ideas to others to seek external support; sometimes we keep them a secret because we're scared of external judgment. But for every idea we don't let be known, there exists the possibility that the world never got to benefit from a possible "missed connection" of mutually beneficial or associated other ideas.
I've never been shy about sharing my thoughts if I think they can help improve things in any way. Often this information has already been brought up and discussed or dismissed but that doesn't mean it shouldn't be shared. You either show that you are on the same page as those who you are presenting the topics to or you show that you need to learn more about the topic. But that shouldn't deter you from potentially sparking another person's interest to continue where you left off. It's a pretty high risk, low reward process as long as you have vetted the idea internally as well as externally with trusted friends.
So that's why my first idea after introducing my introduction to them is for someone to create said idea-curation-then-creation website; someplace that builds off of the positive purpose behind message boards and serves as a melting pot of associated ideas with simple UI and transparent philosophy. After allowing for ideas to be connected, the best solutions will bubble to the top through Reddit-esque upvotes/downvotes then a representative can be chosen and the project can be paid for through crowdfunding.
That's got to be a net positive for the world.
