Its called "suggestions" and not "I write this idea here and in 2 weeks its ingame". 
Neither i opened the suggestion section nor
demand anything emplemented.
This section serves a purpose of feedback, if i understand correctly. And wishes and suggestions are a part of it.
So, if a betatester, as we are, are making a feedback - is it heard by someone? Or is it ignored and thrown away? Or just picked off without comment?
This association confuses and frustrates the betatester and makes him think wrong on the developers as a bunch of elitists who doesn't give a damn on those down there.
Also, a developer is always free to ask the community about the most actual problem. There are a lot of bright minds on forum which are eager to help in development.
So, the point is - the communication between the developers and
betatesters. If a developer read the idea, why not comment it? A little "thumbs up" perhaps? That motivates and makes one think that he don't write it all for a naught.
