Brett Terpstra has been digging deep into tag performance across the Mac ecosystem. Losing Spotlight comments exactly as he describes in this post is what originally pushed me off of tagging in the first place. As with all things Terpstra, there's much to get from his investigation and given some of the changes he points out here, I might just be able to get back into tagging myself.
Tags are generally safe within the OS X ecosystem, from Darwin tools to iCloud sync, but third-party tools can wreak havoc on your carefully-crafted tagging system. As a proponent of tagging, losing tags inadvertently is a fear (and one shared by any tagger). I’d like to keep this resource growing and would appreciate your input.
