[ Adding references to bug 37704 and bug 37705 ]

Reopening. This is being discussed here:

https://en.wikipedia.org/wiki/Help_talk:Interlanguage_links#Capitalization_of_language_names

I have to agree that it's not clear to me how inconsistent capitalization in a list represents an improvement over the previous state. As you say, capitalization is not wrong, and it should depend on the context. If some words in a list are capitalized and others are not, that's just odd-looking. If you look at interlanguage links on any major site, I challenge you to find a list with mixed capitalization.

If this is about drawing from a single source, can we do the capitalization algorithmically while maintaining CLDR as a data source?

This bug was about the capitalization of language names *in general*

For the specific case of the interwiki sidebar, there is now bug 37705.

So I am closing this bug again, any discussion should be on 37705.
