I've posted this elsewhere as well, but I don't think they are two separate disciplines. I think that application authors in many cases should be restructuring their apps to fit content publishing paradigms.

The majority of native apps that I use basically boil down to fancy ways to display or edit document-like data. Music players, maps, terminals, text editors, file browsers, etc...

I think these interfaces would all be more elegantly expressed via an HTML-like model; and the insistence of application developers that they need pixel-perfect control over these kinds of interfaces is just a relic of a world when everyone used desktop computers with a single resolution monitor.

There are of course a ton of smart people who disagree with me on that, so take it with a grain of salt.
