Folksonomies & Tagging

L2TD#6, at the 11th hour...yes, understood the video which was very clear on the difference between a folksonomy (an unstructured categorization scheme), as opposed to a taxonomy (formalised tagging such as that used in Library of Congress subject headings).
I agree tagging is a great way of finding resources, and the cloud method which highlights the most popular tags is especially useful for browsing purposes.
I have set up a Del.ici.ous account - the frustrating part of that was trying to decipher the security code, which took about 6 goes!!! Time will tell if it will prove useful to me; I think it will be a matter of changing my habits, which are well entrenched in "favourites". I am definitely in favour of being able to apply your own tags to websites.
I like the look of Technorati, and will investigate it when I have more time up my sleeve. I was interested in the number of hits on "singing"...
LibraryThing has been around for quite a while now, and has become HUGE since its inception, and obviously a great vehicle for the burgeoning number of bookclubs and book groups around the globe. Maybe PLS could post its bookclub titles on LibraryThing the way Noosa has done; a great way for those keen rural bookclubbers to chat. I was disappointed that I was unable to link to any member reviews to titles on the NoosaBookClubs site.
