One issue with tagging on Web Applications is the tag removal script which automatically deletes tags that have only been used once in the past six months.
This tag removal script has led to untagged questions about low-use services such as goodfilms, openraid, microsoft-answers, and koding. Other sites like Arqade have voted to have tag auto-deletion disabled in the past and it hasn't caused any issues.
Can we disable auto-deletion of single use tags on Web Applications?
