this is very impressive. i'm a little skeptical, however, whether this type of video sharing will get mainstream adoption (like, say, instagram).
people like 3 things re:pictures: 1) take them, 2) show them off, and 3) look at them. this has been true since way before the internet. the advent of the video camera on phones makes 1) happen, but i'm not sure about 2 or 3. for example, i'm seldom inclined to watch any socialcam video that shows up on my FB feed, but i click on pictures a lot more often than i don't.
