What makes them annoying to share? I bet it's more an issue with the UX of whatever app or website you're sharing the link in. Take that stackoverflow link in the comment you're replying to, for example: you can see the domain and most of the path, but HN elides link text after a certain length because it's superfluous.

SO links require just the question ID; short enough to memorize.

		Sure, but the SO link was just an example. HN does it with any link, like this one which is 1000 characters long: https://example.com/some/path?foo=bar&baz=bat&foo=bar&baz=ba... If the website or app has a good UX for displaying/sharing URLs, the length doesn't really matter.
