To clarify my position better:
I don't accept the argument that a near superset means the smaller entity should be removed. If I did accept the argument, then I'd have to go one stop further and notice that
Heavy glitch abuse is also a near superset of
Major skip glitch.
Since
http://tasvideos.org/Movies-C3041Y.html is nearly included in
http://tasvideos.org/Movies-C3055Y.html does that mean we should remove it? I think we're all agreeing
no, and therefore I'm going to focus more on what is best for the user, and not theoretical conceptual problems.
I don't accept the argument that we need to limit tags because of clutter, because that's an argument to improve the site interface, not cripple a useful feature we have. I agree that we need to improve the site interface.
Therefore, to me, whether we should have a tag or not boils down to the following:
1) Does it provide useful information that is not implied by other tags?
2) Does it improve the ability to find kinds of runs on the site which a user may be looking for?
3) Are the runs listed by the tag not nearly ubiquitous, meaning, it can be used to locate an important minority subset of runs that we have. (If it's ubiquitous / majority, just browse the site directly. One doesn't place the word
"the" in the glossary of a book.)
