Liz Lawley: Many-to-Many: social consequences of social tagging. Excellent post, focussing on the social aspects of tagging, and introducing a kinda nasty meme, “lowest-common-denominator classification”, that I wish she hadn’t introduced. I don’t agree folksonomies necesarily represent a lowest common denominator classification – on the contrary. There are many experts out there that are not librarians that can give good tag. But Liz does identify some of the feedback mechanisms that encourage the lowest-c-d behaviour. Let’s just change those feedback mechanisms.
