Libraries and tagging

I've been reading a lot of the articles I'm tagging about social tagging. The implications for libraries are pretty interesting. As a person who prefers a systematic approach to indexing, I was first unsure as to how the tagging would work. It seems so haphazard. But, after reading through many articles, I can see how tagging would be useful, especially in a collaborative research setting or to locate kindred spirits in the research world. (Please, forgive my constant referrals to Cyrillic and Russian libraries, but that is my research area). Especially when looking at Russian-language sites and who tagged them, how they were tagged in other languages, it was very interesting to find the large internet world suddenly became smaller and created a kind of community in which I could participate.
