There's really no need to take such a dismissive tone. The interwiki list comes from a much older internet when connections between wikis was rarer and valuable to support (similar to a blogroll I guess).

Amateur installations of MediaWiki all over the internet have interwikis to Advogato and Drum Corps Wiki (???) that they have absolutely no use for.

What's the problem you're trying to solve exactly? My first impression is that while these wikis wouldn't be added to the default list today, it might make sense to keep them around as legacy/historical entries?

Anyways, c2.com absolutely should stay, it's Ward Cunningham's wiki: https://en.wikipedia.org/wiki/WikiWikiWeb

I see. You’ve convinced me on c2.com.

I understand all that about these being historical. But I think “they’re historical” is not a good reason to keep them. Not everyone who uses MediaWiki cares about the WMF’s noble goals of spreading open collaboration and free content and whatnot.

I see now I haven’t fully answered your comment.

I apologize for the tone. I totally understand the reasoning behind the interwikis being added. It just astonishes me that they’re still here today.

The problem I’m trying to solve is that amateur MediaWiki sites typically leave this interwiki table alone, because they probably don’t even know it exists. It doesn’t necessarily cause any *problems*, per se, but it kind of gives the impression that all these random wikis endorse a bunch of dead other random wikis from 2005–dead both in the literal and metaphorical sense. Anyone who doesn’t know the history of MediaWiki and Wikipedia would not consider the possibility that most of these websites would be there by default, because, again, they’re completely random.
