Tags that have exactly one question are automatically pruned after six months, leaving their questions untagged, and their wikis orphaned. This is problematic on Beta sites, where it's not uncommon for valid tags on niche topics to not get more than one question in a while.
Two Beta sites are trying to deal with the issue creatively right now:
- Let's save our tags! - Biblical Hermeneutics
- Let's save our tags! - Board and Card Games
While both efforts might generate more questions for the sites, and that's good, the communities shouldn't really worry about losing valid niche tags. A third site this has come up (in chat) is The Workplace, where we'd like to use locale tags to identify questions that are depended on local regulations or culture.
Turning off the auto-pruning is already an option, as it's turned off on AskPatents and Arqade.
