Just noticed this yesterday and wanted to share it. In Facebook's IPO Video, they've made a mockup of the NY times and its social share/recommend button. But they've deleted the G+ icon, which is clearly there on the real NY Times page.
I thought it was funny but would love to hear what others think
(I've put it up on Slideshare with screenshots)
