I think personally, the main advantage of this would be that HN urls that I have saved or that I share with others are immediately clear as to what their content is. What do you guys think?
How much advantage does that really provide?<p>If I share an HN link among my Facebook friends, as I sometimes do, a snippet of the discussion is shown, and that (besides my tagline to the submitted link) lets people know what to expect. If I share a link in an email, I generally introduce it to the recipients. What is the use case for changing the link structure of Hacker News? I'm not sure that "immediately clear" is guaranteed by all of the user-submitted titles here, for example.
