I still don't understand what you'd like to achieve. Does the title contains text plus a link that should be clickable ? Is it a title plus a link where the text portion of the title becomes a link pointing to the url ? Is it a url-only title ?
There's definitely nothing in core for this. If you want reddit-style but still keep a text title, the easiest would probably be to use Mason to add a new "url" field to discussions, then use a new extension that adds that link below or around the title in the discussion list.
Also, the link in your first post is still dead as I reported in my first answer. Did you have a screenshot to share ?
