MixBit
From the team of co-founders who originally brought you YouTube, comes the newest stab at a social video app, MixBit ($Free). Similar to some other popular video apps, it lets you record short (16 second) video clips and share them within the app, and on other social networks. It then lets you take other MixBit clips, and mix them with your own, creating remixed video compilations up to an hour long, and sharing them on the web. Unlike its competitors, all uploads are completely anonymous, and there is no commenting system.
