Is the latter tag a legitimate one? If so, should we move questions referring to the former to the tag
logo-language? How do I move the questions?
I think the 2nd usage is probably an incorrect usage, at least in the context of tagging on Stackoverflow. The "argument" that it's used differently on MSO shouldn't hold any weight as they're entirely separate sites with different sets of tags so the usage of a tag for one "thing" on one of the sites shouldn't particularly influence the usage of it on the other.
I'd also prefer, although not being an active participant in questions tagged
logo my opinion doesn't (and indeed shouldn't!) count for much, that
logo remain as just that, rather than
logo-language. Or should we rename
