I completely get what you're saying and agree with a lot of it. Kbin isn't and shouldn't be Reddit but there is a certain amount of user interface tweaking and terminology clarification that needs to be done.
Checkout this link for a user script that helps to fix some of the inconveniences you listed while waiting for official fixes. It's not my script but works well for me.

Great idea as far as I’m concerned.
