Ian@falsepositives.com writes "Lots of discussion going on about 'folksonomies' -- bottom-up taxonomies that people create on their own -- as used in Del.icio.us and Flickr: Adam Mathes has a thesis on Folksonomies; IFTF's Future Now makes a point about problems with folksonomies: no synonym control ( "mac" and "macintosh" on Del.icio.us); no hierarchy and content types; and only simple one-word tags. Joho the Blog notices a discussion about what to call it in Mob indexing? Folk categorization? Social tagging?, and John Battelle links into Taggle and "federated tagging". I wonder if a Google Suggest like system might reduce 'lazy tagging' ,and maybe synonym control when the federation appears. Tag, you're it!"
