There was a lengthy discussion recently on en:WP at
http://en.wikipedia.org/wiki/Wikipedia_talk:Featured_article_candidates#FAC_...
about the fact that many featured articles – at least on en:WP – are about niche topics, while so-called "vital articles" (VA), i.e. core topics that any encyclopedia would be expected to cover well, are underperforming, with comparatively few making FA or GA. Looking at the VA list,
http://en.wikipedia.org/wiki/Wikipedia:VA
topic areas like philosophy, languages and social sciences seem to be doing particularly poorly.
Generally speaking, it stands to reason that articles on niche topics are easier to improve. One or two editors can work in relative peace and quiet, and the number of sources is more manageable. If there are only two dozen sources covering the topic, it's clear where to start; but where do you start with a topic like Information technology?
http://en.wikipedia.org/wiki/Information_technology
After ten years, it's still a start-class article in en:WP, little more than a stub really (though I note it is a featured article in Catalan Wikipedia).
Do vital articles need a special approach to get them to FA standard, perhaps with Foundation-sponsored outreach to universities, formation of article improvement teams involving outside experts, and expert involvement in the FAC (featured article candidate) assessment process? Or do we trust that these articles will improve in time through the normal process of editing?
What is VA quality like in other language versions of Wikipedia?
