I have just finished reading [this really interesting article in which Georgina Laidlaw(http://www.sitepoint.com/bad-web-grammar-bad-ux/) discusses how much of an impact bad grammar (eg: Choose file) can have on your beautifully designed interfaces.
I studied architecture (building, not information) at university and one of the earliest things that we learned was how to print beautifully. No one wants to spend days drafting up a drawing only to ruin it with ugly handwriting. Is this the same idea? On the one hand I agree with her, but on the other, some of the examples used in the article are so frequently used these days that they have become common parlance. Are we taking things a step too far, or is this simply a case of having pride in your work?
