If you go to an item that does not have content in your language, it will look like it has *no* content. That's misleading and unhelpful. As an example, consider http://www.wikidata.org/w/index.php?title=Q26&oldid=57
One thing that would help is implementing language fallback. http://www.wikidata.org/w/index.php?title=Q26&oldid=57 has content for en-gb, we should see that also if our user language is en or en-ca. If there's nothing better, we should also see that if our language code is de or he. Compare bug 36430.
Another thing we can do is (somewhere) show a list of the languages this item has content for. We could (ab)use the sidebar for this, simulating "language links" like on wikipedia. The user's preferred languages could/should be sorted to the top. Compare bug 40744.
The general question behind this ticket is though: how do we make content in other languages discoverable?
