At the Monthly Metrics meeting Asaf gave the example of Ukrainian speakers getting Google results for Russian wikipedia articles even though there are good articles on uk.wikipedia.org.
Can the list of language links be aware of these situations and present likely wiki versions of interest higher up?
I tried this with the ru version of the Ukranian language page, https://ru.wikipedia.org/wiki/%D0%A3%D0%BA%D1%80%D0%B0%D0%B8%D0%BD%D1%81%D0%... , and it seems the link to the uk wiki article is starred (yay), but is way way down a long list, I had to scroll down six screens. Maybe it's ranked higher if your language is ru or uk.
