AppFresh

Any Mac user knows how easy it is to use Software update. Unless you purchased a subscription to MacUpdate or VersionTracker then you may not be on top of updating the rest of the software on your computer. AppFresh is a new (Free) project that aims to make it easy to keep all the software on your computer updated. Since AppFresh is truly brand new (only at v0.2 so far), its developers warn that it is certainly a work in progress. Still, this looks like a great tool with a lot of potential.
