Hehe I think it's good to raise awareness, I appreciate that people correct mistakes, otherwise I might come across as a thick person and I certainly do not want that. When I was learning English, I made that "would have" mistake, my teacher looked at me like a was an imbecile and slowly as if I had mental illness problems, with a shocked look on his face as to how one could possibly make such gruesome mistake, told me that it is in fact "would have". Never again in my life did I make that mistake again. That event always pops into my head whenever I see "would have".
