Got friends returning from a four-year stint on Mars, or elderly relatives who still don't get why Facebook is such a big deal? Want to spark a discussion about whether the site is worth its $100 billion valuation? Then you could do a lot worse than simply screening this video.

Made by online investment platform Kapitall, the 150-second vid takes some of the most eye-popping stats about the social network and delivers them in a pleasing animated infographic-style format (not to mention a thumping proto-80's style synth soundtrack).

The video is a little disingenuous in one way: it suggests that "the rest of us" can easily get in on the action whenever Facebook has its IPO (likely coming this summer, though the much-anticipated launch seems to have been delayed by Facebook's billion-dollar acquisition of Instagram).

In fact, as we pointed out back in February, you're unlikely to get in on the initial frenzy unless you're an employee, a celebrity, a business mogul or one of the deal's underwriters. Investing in the secondary market for Facebook stock is also fraught with regulations and complications; you're better off waiting on the sidelines.

But plugs for Kapitall's business model aside, this is one of the better summaries of the social media frenzy that we've seen. If YouTube wanted to build a time capsule of videos that capture our connected age, this would be a worthy entrant.

Not least because everything we know about the way the world is going suggests the viewers of the future will have an extremely limited attention span.
