> Every community is different, and people need to show different information on their userpages for each community - e.g. showcasing their featured articles

The communities are different, but the user is the same. At best you'll have a translation of your intro message. Some things can in fact be automatically translated, as shown by the "profile" page above the user page,  I've never tested it,  but seems to be global.

Things such as "showcases" and so forth, are part of the wiki they are in not really part of the user page. Therein lies the problem with wikis, no clear separation of things. A "profile" is different from a notice board, or a scratch pad, or whatever else people use their page for. Mediawiki developers used a lazy solution to name every damned thing a page, which is why "talk pages" are a mess.

Personally, I don't waste any time with user pages exactly because they have to be updated everywhere, and I wouldn't really bother even if some users edit war on my user page in some distant XXXX wiki I've never even heard about. At best I'd go there to remove notifications for that damned page or ask wikia staff to lock it.

Just tested it, apparently, one is not attached to a wiki until one visits it, or edits it?
