In its whole I find the article quite funny and witty but at the same time a bit to complicated. It has a feeling of disorder over it which is a bit to overwhelming. There are so many dates and names with people that did or said things which confuses me a bit too much. On the other hand the jokes you do have are indeed funny and I find your footnotes rather amusing. I'd suggest to remove a few of the people or events mentioned and ellaborate those you keep.
I really fancy your concept. The whole genoa versus pisa thing is a good idea. I think my only suggestion here would be to perhaps add a few paragrafs about the maths behind the Socks or the religious meaning or something like that. Basically you stick with historical "facts" when you could make it more than that. Other than that i like the idea. I must admit I've been thinking for a while if you could use something other than socks but havent come up with anything better =)
Prose and formatting:
In accord with my own skills in the english language I find your prose sufficiant indeed. I have so far only found one error where you wrote "an" instead of "a" somewhere in the beginning. As for the formatting you keep it simple with fitting titles. Maybe a tad too simple. Don't be afraid to use headlines and under-headlines to i.e format your construction periods. One thing that bugged me a little is that you have too many links in my opinion. All those blue words everywhere just kept stealing my attention.
3 is maybe a bit harsh but you do only have one picture and I dont find it particularly good or funny. I actually dont think you need a picture of the sock pile itself as imaginatin will leave people with a funnier thought. Maybe you could have a few pictures about other events or people named in your article.
As for your imagination - thumbs up =)
I'd conclude that this article is good as it is but could defintely reach new heights with some tweaking. Mostly by making it feel more "organized". Great job!
