In case you missed it, last night Plone 4 made an appearance on NBC Nightly News! Its inclusion was happenstance—it came during a demonstration of Google's new instant search feature, with a search for "how much faster is it." The first result was Hanno's blog entry discussing performance improvements in Plone 4!
(Thanks to Darci for the screen capture.)
You can still see the results yourself, although Plone is now second after a blog post about Google's instant search.
