How to execute code on cursor move

I want to check a text property and display in the minibuffer depending
on context (in my case, on an org-link).

This is what I have so far (working):

(add-hook 'post-command-hook
            (if (eq (get-text-property (point) 'face) 'org-link)
                 (get-text-property (point) 'help-echo)))))

Is using the post-command-hook a good idea?  Is there something better?
As you can see, I'm trying to get the link target; are there better ways
to do this?

Thanks for any ideas.
