I clicked your signature in note you posted to my talk page which is a beautiful color with distinctive typography. It led me to the page I posted on. I assumed that was the page you wanted me to post on since your signature led me there.

I had not thought of the mutability of Wikipedia articles. That is a good reason to prohibit using them as references. 

I agree that ""if Wikipedia only cited itself, it could say anything at all.""(emphasis added by me) But Wikipedia does not cite only itself. And in fact the Wikipedia reference I used was to a sentence with an outside reference. Although I was careful about that outside reference I am sure that many would not be. So I will agree that the outside references do not invalidate this argument against self-references.
