When I first opened Technorati, it looked like a difficult site to navigate through. Thing 14 instructions said to check out popular blogs, searches and tags. If they didn't have the link right there, I don't think I would have been able to find it in their website. Looking past that, there is quite a lot of info on this site. I did search "School Library Learning 2.0" and "Classroom Learning 2.0" and found many blogs and blog posts relating to these topics. However, when I searched tags I got no hits for either of them. I really enjoyed searching the popular blogs. Boing Boing was really interesting. I can't believe that they have editors, senior editors and whatnot. Is this a business for them? If not, when do they find the time to keep up with all the latest info that is available there?
I guess I didn't really understand the concept of tagging until I read chapter 8 in Nancy Courtney's book. The advantages that I find to be most important regarding tagging is inclusiveness, currency and low cost. With inclusiveness, people can find those rare allusive topics that controled vocabulary may not allow. For example, if you practice shamanism, thereare many buzz words that only shamans would know. Currency is important too. It takes minutes to update and create tags. It takes a lot longer to update "a large taxonomy". Low cost seems to be the biggest advantage for obvious reasons. Some disadvantages are the lack of hierarchy and gaming which is like spamming. There are no relationships in tagging. With gaming, anyone can just make many many tags for any content. This is a serious tax on the tagging system.
Tagging for personal reasons may not be a good idea for me. At work, I file a lot of information and I find that what I file stuff under depends on the mood I am in. I am a very inconsistent person for which tagging probably wouldn't be helpful.
