That's actually a great idea! :) Haven't actually thought of that. Two things in mind: rewrite links but provides copy-paste for the original link (think about XSS from clicking a link on tweet and people want to look at the link before clicking it) and (2) HN's rewrite/shortened link must do dynamic cache url retrieval; not static. I think Google's cache link is different as cache is updated.
