Startup for finding ideas for startups

I thought about what to do in the field of software so that to make all the money would be a really useful service or program, and that's what I thought up. To find a startup idea, you need to make a website :)
Which one?
I think many of you have thought about the topic of a program / site / service that you could write and earn / benefit people. So, it would be great if people would somehow say what they need. For example, one of the greats of our time said (not a quote) - if you want to earn money, take up something that people simply hate to do, and sell it as a service.

So, you need to make a site on which people can:
- constructivelydiscuss the shortcomings of existing solutions in the field of, for example, software;
- give practical advice on the same topic;
- rank yourself (well, you understand - the best answer, the hottest problem, etc., etc.).

And it’s useful for people, and for startups to help. What do you think? Or is there already something similar, but I overslept?
