Your advice is good, and I agree that you didn't use specialized software to reverse the blur, but this

That gave me a laugh. I don't have any experience with Mathematica, but everytime I see it mentioned (usually on HN) I'm amazed at the sheer breadth the system is capable of. The amount of use cases and possibilities blows my mind.
The other answers are also very clever and interesting. There are quite a few ways to determine whether the goat is up or down, and some are very simple.
If it is in the installable version now, it will be in Wolfram Alpha in 5 years if you can guess the right command, and in 10 year Wolfram Alpha will just automatically select the blurred part and make a fake unblurred versions of the jpg.
