I agree with what's been said here, about not using it too much, but at the same time not using it like it's the plague. Don't flavor your words way too much, otherwise the emphasis is lost for the times when you WANT your reader to actually pay attention to those smaller details. It really just depends on a case-by-case basis, but I think the best way to approach it is: don't overuse it, but don't go out of your way to avoid it.

Like with what Janobii said, sometimes you don't even need a tag if it's a back-and-forth conversation between two people who have already been introduced in that little section. Unless you're trying to add some sort of emphasis on a conversation like that between two people, it's not a bad idea to just leave it as how Janobii stated.

Just don't think too hard. Moderation is key.
