I have a 100% success rate report posting about bugs in this thread and then count on people taking it to development to get it fixed in the following release. It's my impression that constructive feedback is generally well received. Not automatically accepted, but still well received if written in good faith.
I would be careful about using the word "insane" online. The last one to call me insane regretted it a lot because his post got called out for not reading my post and instead attack me for what he imagined I wrote, but didn't actually write. He never objected to being called insane for believing the "facts" he posted, so I guess he is insane now. I will refrain from commenting on the user name used when calling people insane this time.
