In reply to Miroslav Glavic.

I recently came across what's perhaps a good way to think about what makes an app different from the normal website/webpage use cases. If it's mostly links and text, that's probably just a webdocument, i.e. not an app.

Anything other experience that offers more interactivity can be considered an app (why not?). I think a blog with a comments section in itself can be considered a web app in the broadests sense of the word. WordPress is already an app platform because you can run a social network, forum, ecommerce site with a plugin, it's almost turn key.

When it comes to platform, I don't see why you wouldn't call apps for mobile devices native mobile apps, or mobile web apps. Alongside those you have desktop apps, regular web apps and tv apps. Would be cool to see more desktop apps that interface with WP.
