I’m still not sure most of us would agree that the amount of thought and time put into tagging systems and tagging resources is worth the while.

I talked about some issues related to making and using tags at this year’s South by SouthWest Interactive Conference (SXSWi). Let me start out with some of those ideas here and add a few new ones just to set framework for our conversation:

Tags are good because:

  • They show a user’s view of the data
  • When in a hypertext system, they provide easy ways to sort and browse data
  • They help with search because they may offer additional keywords for a resource that aren’t in the original resource
  • Experts are not good at describing every possible keyword or concept that may apply
  • Tags are additional (meta)data that can be analyzed by information retrieval systems

Tags are bad because:

  • Experts may be a little better at describing resources (assuming that experts are the one posting and creating the resources in question)
  • Tags may be too focused on one community of users for wide utility
  • Once tagged, a dynamic resource may change, but the tags may not necessarily be updated to reflect this change
  • Tags are just another system of resource identification to spam, spoof and game (especially tags as links to Web pages)

Do you agree? Disagree? What did I leave out?
