Q:

Any [helpers] for putting the [helper] out of its misery?

Just stumbled across some helpers in this question.
Looking myself, there's also a lonely helper who left the crowd.
Can we please exterminate them?
(The tags are very vague and meta, and they just cry out for it.

A:

Looking at the questions, it seems like "Helper" actually is the correct terminology for meteor.  (According to comments, a new meteor-helper tag has been created and added to the intersection of meteor and helpers.  So that's dealt with.)
And all (that I saw) of the rest came from someone typing a sentence help me frob blah pls into keywords, and the system suggesting "helpers" as the closest match to "help".
A couple of the questions should be using helpfile instead, because they discussed parsing/viewing/browsing help files.  Again, someone probably typed "help" in the tags and it expanded, although this time they actually did mean it as a keyword not a sentence.
It seems like "help" ought to be a blacklisted tag, not a missing tag.  Because having it expand to any suggestion, helpers or otherwise, leads consistently to wrong outcomes.

A:

For those pointing out that "helper" is a correct terminology in some frameworks, templating libraries, etc., I acknowledge that, but I doubt the value in an actual tag devoted to this particular mechanism. It makes more sense for it to be tagged by the framework/library, where it will garner some attention. The fact it's related to whatever the framework/library calls a "helper" doesn't seem significant enough to warrant a full tag. Additionally, the name is so utterly nondescriptive that it could mean virtually anything depending on the framework/library, and thus adds almost zero value to the question as a tag.
While I'm usually cautious about the following argument against tags, I think it actually makes sense given how vague the name is. You can't be a "helper" expert because "helper" is so ill defined. Certainly, this also means that the helper tag can't stand on its own; it would need additional tags, making its value even more dubious.
I'm all for burnination.
