I can't see how Flipboard, which describes itself using the tagline
Your social magazine.
would be a good place to host or view Stack Overflow content.
The Wikipedia page describes Flipboard as
a social-network aggregation, magazine-format application software for Apple touch-screen devices, including the iPad, iPhone and iPod Touch.
Considering Stack Overflow is not a social media or social networking site, we don't seem to fit very well within their model.
And even if it was a good fit, I don't think this should become an official feature. There is a public API, so you could always write your own templates/application.
What's wrong with the mobile theme you already get when you visit the page?
