Over a third of our present 222 questions are tagged gramática, many of them followed by something more specific like ortografia (our second most used tag). Grammar is clearly one of the site's major topics, but how should it work as a tag? As it currently stands, we could split the site's questions as:
It fells to me that the tag is either too broad, or being misused. Is it used in other language sites in the network? Is there any guideline we could build upon?
I agree that gramática is usually too broad. On the English SE site we try to use more specific terms than that whenever possible, but new posters are constantly using the grammar tag. We clean these up when we have the chance.
Any collocation of gramática and ortografia is somewhat peculiar, in that “correct writing” is not usually consider a function of grammar per se. But it also happens on ELU that people use them together, at least until we edit them into something that fits better.
