Website for people to post their pain points, problems etc. in relation to their industry. What do you think? Does it already exist?

So first of all i can't find a website that already does this. So please let me know if this already exists!

My idea is to create a website where people from all kinds of industries write down and post their pain points, things they wish was invented, things that they wish could be automated, ways that could make their jobs easier etc.

Have a basic system so people from the industry who agrees with them can upvote their ideas, so people from outside the industry can get an better idea of what's actually a recognized problem.

You should obviously be able to contact the person who wrote the post, and pitch a solution or whatever.

I think this would be a great way for people who don't work in a industry to get an insight into possible market gaps.

Please let me know about your thoughts
