You might want to put a list of the day's top tl;drs on your landing page, or def. under "want some". When you roll over the title of the story, you get a floating tl;dr.
This would encourage skeptical users to do what you want them to do (drag that link up to the toolbar).
Thanks!

This is something we are indeed working on, but we put off the launch for too long already and really wanted to get feedback. You're right though that discoverability isn't great as it is.
Try it on most links here on the HN frontpage though, we're doing them for you today!
