While my exposure to Xitter is limited to Xits that others post and very occasionally reading an associated thread I think there's *some* merit here. URLs can be bulky and making them short has it's merits. However, it also reduces the information--what they are seeing as "engagement" is often going to be people clicking it, seeing it's garbage and closing it. Thus I would favor a middle ground: Short visible URLs but the whole thing is displayed if you hover over it. I have no good answer for mobile.
