Most normal users don't understand what URLs are, so I don't think this is a bad thing. This actually makes the UI more consistent; the address bar is always a way to search or go to a URL.
An anecdote: my friends girlfriend was reading an article on mobile safari and wanted my friend to read it. Instead of sharing the URL, she actually took screenshots and messaged it to him! We both found this fascinating! I keep seeing this sort of behaviour on Twitter and Facebook where people share screenshots of tweets and posts instead of the URLs.
