Startup Idea : a place people can give they complains and share

Think of all the people that are good thinkers when it comes to what is wrong, and what is missing. When people saying that this is a problem, i hear = potential business and helping them around me ( including my self). So we could make a website, app, or something that is easy for people to get to. Then we let people write they problems down. Then we know what people having struggling with. Then we can brainstorm about a good idea to solve that problem. Sometimes is hard to come up with an idea if the idea isn´t helping a real everyday problem.
