Thanks for letting us know, there is a section for that however - using the chrome plugin you can view all incoming and outgoing upvotes under the "Votes" tab. Pretty clever stuff.
Unfortunately as you've been busy voting so much (don't forget the comments too) your vote has no value - I thought it might help to point that out.
With that in mind I put together a quick post including a rather informative diagram, otherwise known as an "infogram", so you can better understand how it works.
