I don’t mean to offend, but I wouldn’t call this a rig. Not a completed one, at least. This is just some bones with a mesh weighted to them. To make it an actual rig you need to add controls and other such things to make it easy to animate.
For example, here is a simple bunny rig I made: http://blenderartists.org/forum/showthread.php?t=100300
Notice how I’ve set up (hopefully) convenient controls for the animator to use, and hidden the parts of the rig that the animator shouldn’t have to know about.
When you make a rig you are quite literally designing a UI for the animator to use.
Ok then I will go away and come back with a better rig (or if you want you could have a go at rigging him
