I'm all for opening up oneboxing, but not for creating yet another standard.

There are already two competing, widespread standards for onebox-like functionality: [oEmbed](http://oembed.com) and Facebook's [Open Graph](http://ogp.me)<sup>1</sup>. If Stack Exchange is going to do this, they should adopt one of those instead of re-inventing the wheel.


[![Fortunately, the charging one has been solved now that we've all standardized on mini-USB. Or is it micro-USB? Shoot.][1]](http://xkcd.com/927/)

<sup>Note 1: what you're proposing is pretty close to Open Graph anyway.</sup>
