The Dilemma of Capitalization

I read the blog about On studying history/History and I agreed. Capitalization is a subject that is not universal it depends a lot on what newspaper are you writing in. Normally if I came across the question whether to capitalize a class or not I would probably said that I wouldn't capitalize it. "I'm not surprised. Capitalization is one of those areas very much subject to fashion and change" (http://david-crystal.blogspot.com/search?updated-min=2009-01-01T00%3A00%3A00Z&updated-max=2010-01-01T00%3A00%3A00Z&max-results=28). I really like how he stated his opinion and successfully supported it like the maxim above is supporting the constant change and not knowing of capitalization. Capitalization according to him will constantly change with time so there is not a way to make a global rule of capitalization.
