My company is interested in hearing your recommendations for wiki curation best practices. We've been running an instance of Confluence since 2005 without an official cleanup/curation policy to help purge old/dated content.
We're hoping to mine the confluence community for things that do/don't work before implementing an official policy to help maintain the usefulness of our wiki with 7 years of content.
Things we're considering:
1) automated notification to page owners of pages that exceed certain thresholds of "freshness" to ask them to review and update, or delete.
2) automated cleanup (move to an archive space, or outright deletion) of pages via a plugin that uses a variety of metrics to automatically select pages older than a certain date if certain criteria (labels, view counts, etc) is met.
3) manual review/cleanup effort.
Any wisdom you can share would be appriciated, thanks!
