Interesting idea. We've got some work planned to do this kind of thing for citations (you feed it a URL, it inserts a nice <ref>{{cite web|…}}</ref> block), and links to internal or interwiki targets get auto-converted on save (so [[:en:Foo|Bar]] not [https://en.wikipedia.org/wiki/Foo Bar]), but we don't do this for pasting into the surface. Maybe something we could do in the future?

This could potentially inform the VE UI for citoid;

I.e. we could have have one reference dialog, (i.e. the basic reference dialog) and then if a user pastes a link *into* the reference dialog, that inserts the citation guessed from the link. And then keep the drop down menu for individual templates in the ref dialog.

This does take some user discovery; however, I see this commonly being done with references already- i.e. a ref tag containing only an unformatted url. So it seems people are already just pasting links into the ref field and this is a natural enhancement of that work flow.

This, by the way, is what both G+ and Facebook do for links as well, not just Quora. So there may be already some user comfort with a pasted link becoming formatted in some fashion.

Hmm. Right now we're taking newly-created external links and displaying them as auto-numbered link nodes; having this as a secondary mode to fetching the <title> could work, but… I'm not sure.

I meant not only external links, but pages in the same wiki, too. It's anecdotal, but I see newbies adding http urls to other Wikipedia article instead of using square brackets, and this should be DWIMmier.

Those already get converted to internal (well, interwiki) links, though…
