This is called user feedback. If Open Source community could stay aware about this it only could improve the quality of the apps.

This is what is happening every single day in commercial world.
Devs are struggling to understand some user requirements, sometimes they are just plain stupid, true. There is no way that user can understand development process. But in other hand there is no more useful information source. They care about tangible stuff, no mater how beautiful it is under the hood.

As long as critic is constructive, giving you power and motivation to improve your stuff. If not, you are not ready to call yourself developer... maybe coder.. but not developer.

We definitely need developers here.
