Subha,
If you check
WordPress.com it shows all available Indic languages.
If you check
WordPress.org, I think it is showing only Tamil (may be
because as you said it is the only translation available and that too for
Srilankan Tamil : )
But the point is: Even if you show all available Indic languages without
resolving to the level of state and language, it is still good.
//non-controversial?, who are the ones who could decide on such a high
impact sitenotice based on geolocation, this list?, meta admins?, English
wikipedians of India? Though there is nothing wrong with intent, keeping
banners for long needs some consensus.//
Sites like
http://www.google.co.in/ highlight the available languages and
it makes perfect sense for usability. If keeping a site notice for ever in
all pages is a problem, do it only for the pages where there is an Indian
language version is available and show only the links for the languages
where a corresponding page exists.
