I made a compelling case against the technology tag in my previous attempt to irreversibly dissect it into see-through thin slices, didn't I? Well, I wish I could take that back, because things have changed around here since then;
Since the last time we discussed this (early days of public beta), we've extended our scope to also include planetary-science, orbital-mechanics, we also received many more questions about procedure, human experience, health, and it appears we even embraced celestial-mechanics, as long as it relates to spacecraft. All but the latter, and I didn't include many more (atmosphere, medical, interstellar-medium, terminology, history, life,...), are not necessarily directly related to technology and most of them could even be featured at the opposite or only slightly intersecting groups in some Venn diagram, with many example questions that use them fitting in between or even excluding technology.
Putting it differently, I now think that even as broadly scoped as tag technology is, it now serves a purpose as a distinct tag in its own right. Let's consider a few example questions:
Emergency plan for Soyuz missions
Does Star Trek's adherence to naval tradition have roots in NASA or earlier real organizations?
How are accidents involving rockets and space vessels investigated?
Why do they say "go" and "no go"
What is involved in clearing air space for an orbital launch?
Why are three cosmonauts required to move a Soyuz?
How are multiple launches handled?
What are the procedures aboard the ISS in the eventuality of a loss of a crew member?
Yes, I just copied a few questions listed under procedure, nothing too fancy, but I can imagine how some of these questions don't ask about technology at all. Similar could be done for other non-technological tags, some of which I listed before.
So I'm now against abolisment of the technology tag, because with our site's now broader scope, it helps us clarify what questions are focusing on better, and it isn't necessarily already implied and thus obsolete any more.
