So on your last point, I found something sneaky you can do to people:
The answers have a sort order, controllable by tabs below and to the right of the question. These go to the same page with a GET arg to change the order. The trick is that these are sticky - browsing to one saves it as your preference. So if you post a comment to a question and include that arg, it'll switch the whole site for whoever clicks it, without telling them.
One of the options is "newest first".
The intended outcome here is that you post your own answer, and leave a comment on the most upvoted one summarising your concern with it.
And that readers don't just pick the most upvoted one, (even though it's obviously the site's design that they should be able to do that).
