Thanks for your help everybody!
Since we seem to have covered all the major cases I'm locking this for posterity. If there are any other tags that should be renamed please request it in a new question.
Just a few minutes ago we recieved an announcement that the maximum tag character length has been increased from 25 characters to 35 characters. Hooray!
I figure it's a good idea to see if there's any tags in our system that should be renamed to take advantage of that new limit, that we had previously squashed down to fit in the original 25 character limit. Please respond with your suggestions here of tags we should rename! Once it's clear that rename is a good idea & the community seems happy with the rename, us diamond moderators can use our ⚡ phenomenal cosmic powers!! ⚡ to rename the tag swiftly with minimal disruption to the front page. We'll leave a tag synonym pointing from the old tag to the new one unless there's some reason we ought to not do so (thanks Baskakov for suggesting that).
Let's stick to one tag that should be renamed per answer, and please suggest what we should rename it to — we might revise that and go with something different, but your suggestion will help us understand the nature of the rename that ought to happen.
IIRC there's some World of Darkness tags that we shrunk to fit, and a doctor who tag we could potentially rename if it would be a good idea.
Some clarifications:
- We can undo the tag rename if it turns out to have been a bad idea, or re-rename it. The best thing we can do is make sure to avoid making such a mistake in the first place though, so please do vote and/or comment to show your support or bring forward concerns with a given rename.
- This won't revoke any badges or tag badge progress. Those of you who have earned a taxonomist badger keep your badger no matter what happens to the tag that earned you it. (The rename might interrupt earning a new taxonomist badger for that tag, though.)
- Renames unrelated to tag length constraints should be proposed in their own question, not here, please. :)
- The 35 character limit isn't adjustable by us, and probably won't be increased further for a long time due to some architectural concerns in the software that powers stack exchange.
