Ask HN: Is there a side project ideas board?

I have a day job and I want to start a side project, but I'm a bit of an introverted person. I looked at a lot of growth and marketing YouTube videos and almost all of them suggest reaching potential customers. A lot times you don't even have the idea and the gurus just suggest that you reach some random people that you know and ask them if they have some pain points in their business. Things get complicated, because If you do, you often get refused that you just want to sell them some app they don't need. So I started to think that maybe some side project ideas board would be great.
