How do you know which users are worth listening to?

Every user has different opinions about what your product should do

Some want new features, some want a better design, and others want things that might not fit your product at all

Trying to satisfy everyone can make things confusing

I think the challenge is understanding which feedback points to a real problem shared by many users

For SaaS founders and makers, how do you decide which user feedback to act on and which to ignore?
