Somebody recently posted on the English Wikipedia's "Help Desk" with what at first sight appeared to be a technical problem with skins: they could not see "the most modern 'standard'" while logged in. [ http://en.wikipedia.org/wiki/Wikipedia:Help_desk#Display_irk ]
I think, however, that they are just being confused by a rather unhelpful choice of name - if you select "Standard" as your skin, you get not the current default (which is called "MonoBook"), but the previous one. It's now become a name for something that was previously essentially nameless.
As I went on to say in my response, it's probably not a very good idea having something called "standard" that's not standard any more - perhaps we should try and come up with a "proper" name for it. "Classic" would be a possibility, but not a very good one, since we already have a "nostalgia"; "phase3" would be a bit dull (and meaningless for most users)...
So here's my challenge to you all (developers and users alike, I hope I don't annoy too many people by cross-posting this): come up with a name, in retrospect, for the skin which didn't need a name until MediaWiki 1.3, because it was just "standard".
