The Taboo should have been taboo for J.K.

Let's talk about the "Taboo" for a moment.

We're introduced to the Taboo mid-way through The Deathly Hallows. Ron explains that Voldemort's name has "been jinxed, Harry, that's how they track people! Using his name breaks protective enchantments, it causes some kind of magical disturbance... Anyone who says it is trackable!"

First of all, I agree with Ron. Voldemort and the Death Eaters make very clever use of the Taboo since they know that only people who are members of the Order of the Phoenix or might otherwise prove a threat to the Dark Lord still use the name "Voldemort". The Death Eaters refer to him as "the Dark Lord", for the most part, while the good guys and innocents all prefer to use "You Know Who" or "He Who Will Not be Named".

So placing the Taboo on the word "Voldemort" will provide excellent results for the Death Eaters: they will be able to track really problematic people with few false alarms.

Clever. Very clever.

But let's look at the Taboo itself. As explained in the book, the Taboo allows me to place a jinx on a word so that if you use that word you lose all magical protection that you have sought to place on yourself and I can track where you are.

Wow. That's a pretty powerful tool. And we see it work very powerfully later in The Deathly Hallows when, despite all of their tried and true protective enchantments, the Taboo exposes Harry and the crew to the clutches of the Snatchers.

So why isn't it used more often? For example, if the Death Eaters were so interested in finding Horace Slughorn prior to the events of Book Six, why didn't they just put a Taboo on his name (or on "candied pineapple") in order to find him? Sure, there might be some false alarms but they'd probably be worth the trouble.

Why would they not put the Taboo on the names of all of the Order members in order to find them and break down the enchantments protecting them.

And remember, at the start of The Deathly Hallows, Snape tells Voldemort that, Harry will be taken to a safe house that has been prepared for him and has been "given every protection that the Order and Ministry together can provide". Snape concludes: "there is little chance of taking him once he is there."

Wait a minute? If capturing Harry is job one and they have a weapon as powerful as the Taboo available to them, why wouldn't they try jinxing a whole bunch of names or words associated with Harry and the Order, accepting that the large number of false alarms they might face would be well worth the possibility that the Taboo would eventually beak all of the protective enchantments the Ministry and the Order have put in place and allow them to track and capture Harry?

Let's just say they Tabooed the word "Hagrid"? Wouldn't that be enough? I mean, not that many people would say Hagrid's name about then but members of the Order are sure to do so. Why not use it to track Harry and strip away his protections?

Again, I think the Taboo is a very interesting idea. And I agree that the Death Eaters were very clever to have used it to expose members of the Order.

But, like the Time Turner and Felix Felicis, I wonder if it wasn't a dramatic mistake for Rowling to introduce the Taboo into her world. Once she establishes that this powerful tool exists, she has to consider when and how it might otherwise be used to effect in the story.

Then she has to account for why it was not used (it is an extremely difficult jinx and a person can only cast one Taboo at a time, for example).

If she doesn't, in my opinion, she undermines the drama of her narrative.
