This is from a pc only user so it may be taken with a grain of salt but I think it would be the same for any game platform. I read a lot of console posts because I usually hit new posts button and it doesn't make a choice on which I want it just gives all new posts.
"All feedback, positive or negative is welcome." is nice but consider it this way. If you have 10,000 posts about your game, if 9,999 are "Great game, I love it" etc...and 1 post is "This is so frustrating. Everytime I enter the dragons cave and jump, if I hit the button to spin around my game brings me back to my house and I lose all my progress" which one will be more helpful (well a little helpful anyway) to the dev. I suspect they need to know more about what is not working than what is. (Not 100% true but close enough) and the salty posts are going to be the ones telling them what is not working.
That being said they do need to know what is working too. Not only to know that it is working for most everyone, but devs are human too and it is nice to hear something you have done is enjoyable to other and that your work is appreciated.
As mentioned I only play on pc and I may have this all ass backwards.....and I am sure someone will soon straighten me out
