By sub-heading, I mean the words "web fonts; beta" used in the provided example.

I think its offered for free by the Google Web Font service, but they offer so much; it's almost impossible to find it.

Any results will do! Thank you!

I want to know too...

After a more elaborate search under the Google Web Font archive, it looks like the font is called News Cycle. I'm not 100% sure though, but it looks the same for the most part.

Roley is correct.
News Cycle is the font.

actually pretty close to this - think it may be one (I think they use many different ones - this one for the Web Store logo)
