What Your Choice of Dialogue Tags Says About You | Jane Friedman

One way to look at it is to consider any movement away from the exclusive use of said or asked a step away from the very "best" writing, from the kind of writing intended to be considered "literary." If you spend any small amount of time examining blogs or books on writing, you will find that this is a very common directive: use said, asked, and nothing else.

There are a number of reasons for this, but the most common works in conjunction with that other famous maxim: show, don't tell. If you use the word ranted to describe the speech act of one of your characters, you're telling your readers how to understand what is happening rather than illustrating through action and dialogue.
