Facebook has many great "official" apps, and one of them is Facebook Video.

It stands out because of its mobile aspect. Aside from uploading videos from your computer, you can do so to through your mobile. Many of my contacts have shared videos taken with their smartphones and PDA phones mere moments after they've recorded it. Which means that, if I wanted to, I could stay up to date with the more prolific amateur Spielbergs.

And it's a more interesting experience than image galleries. Pictures are worth a thousand words, while video is literally and figuratively worth a thousand pictures.
