> Imagine how tedious it would be even to use a relatively simple discussion forum like HN if you had to wait for a full page reload every time you hit a voting button or expanded/contracted a thread.

You don't need a full page reload to implement voting; that's what the 204 No Content response is for: your browser sends the vote & doesn't refresh the page.

That's a fair answer in the specific case of voting, but it doesn't help in the other situations I mentioned.
