"To illustrate why this is an issue, I posted this reply explicitly asking
for feedback on two items. How many replies did I get? One. A single reply.
Oh, there were more replies to the thread afterwards. But they were too

above list to actually discuss the open issues with the proposal."
The problem here seems to be quite endemic and I don't think there are any simple fixes. This seems to be a cultural problem. I'm not even sure how to tackle something like that.
