On StackOverflow and many of the other StackExchange sites, it makes sense to normalize tags to all lower case since there's no real distinction between,
perl. (Some would argue there is a distinction, but practically we know what is meant.) But reading the tags on the Philosophy site, I'm struck by the number of proper names we use as tags and how strange it is to see
hume, rather than
Hume. The first seems a nonsense word and the second is an 18th-century Scottish philosopher.
popper are also completely different, though I imagine we'll have few questions about machines for making snacks out of corn kernels.
At issue isn't so much the meaning of the tags, which, while confusing at first, are unambiguous, but the aesthetics of the site. Professional programmers are used to seeing normalized capitalization, but I'd imagine professional philosophers would be put off by the names of philosophers being all lower case.
Does StackExchange support capitalized tags?
As an aside, making all tags capitalized (i.e.,
Induction) would not be inappropriate here, I suspect. All caps (
PLATO) would be too much, of course. If we had questions about e.e. cummings we might run into trouble, but I'd say capitalizing all tags would be a good choice too.
