A folksonomy is good for an organization because the non-traditional persons who are tagging information create a key-in for the traditional, taxonomy persons to get the inside scoop (for lack of a better phrase). Within a taxonomy, the CEO, for example wouldn't know how or what their lower scaled employees think. However, if there was a impromptu blog started on the negatives and positives of this CEO's company, he would then be able to find out insider info. The folksonomy within an intra net is a smart way to look for impairment and ways to solve them.
What I would like to see is an online folksonomy/evaluation for Marymount. Students and teachers could blog complaints and delights while using tags. Filling out paper evaluations at the end of each semester does help and makes the student feel worth while, like they have a hand in choosing teachers. However, when a student is finishing a final or is in the last day of class their mind isn't keyed into the overall status of their professor. My idea for an online evaluation would be a web site that runs for only a specific amount of time once a semester is over. That way students/staff/faculty have leisure to think about what they want to say and are not forced to do it under a small amount of time. Tags would be labeled students, majors, staff, events, etc. Although the site would start unofficially, the thoughts would initiate solutions or praise to the directed areas.
A folksonomy would be very organizational for a group of photographers or a sorority. The photographers would be able to label, list and easily find photographs from a certain kind of shoot, model, or photographer. The sorority's could do the same except they could expand to not only service the chapter in their school, but the state and eventually, country. Really, the possibilities are endless. Laura understands that it's about bringing people together. Everybody get together, try to love one another right now. Right Now. Whoooaaa...aaho.... Photographers could find inspiration, ideas, contacts, and sororities can do the same.
If you still don't exaclty know what a folksonomy is, and how it is useful, Chris gives a good explination, equipped with examples.
