I use 'uppercase' (as it's meant to be used, at the beginning of sentences, names, and so on) because I love literature. I love books - old books, new books: good books - and I love writing and words. I guess reading a lot of wonderful books one can't help but admire language (the English langue in my case) and respect its importance and power to convey ideas to a person's mind and, sometimes, (more often then perhaps is realized) to change cultures.
So I suppose I use uppercase - and every time I don't some other part of me goes back and capitalizes immediately - because I feel like it's just one little thing I can do in tribute to a thing I admire and love greatly: the English Language.
I don't think it's wrong to not use caps, I just don't personally, and for some reason I was thinking out in my head: why?
