At a high level, one of the main goals in uProxy is to lower the bar for indirecting your traffic.

It isn't meant to provide anonymity, or to resist targeted attacks. If you're wondering where to place it, there has been some discussion on how to make it a first hop 'pluggable transport' in the tor browser bundle. Mostly though it's meant for making indirection a thing that is approachable for the majority of users who aren't at a stage where they need tor.

The part I'm most excited about is that social network support is built in a reasonably extensible way, and is quite close to supporting a much wider range of methods than what has made it into the current version.
