[IxDA Discuss] categorising tags?

[Sunandini Basu]

Is it a good practice to categorise tags?

as far as i know, tags are meant to be non-linear. del.icio.us has 2 ways to
organize tags - alphabetically and by frequency.
I was surprised to see MSN organizing tags by grouping them under
categories<http://qna.live.com/BrowseTags.aspx>.


doesn't that totally go against the whole concept of tags?

Best,
