Tagging and Bookmarking

Easy and fun. Also, this is an area where it is very evident that Web 2.0 is an exercise for the "whole class." Everybody gets a little input as to what their take is on the particular website. With the tags that I've looked at, most people are on "the same page," however, there is certainly a lot of creative interpretations that I would not have necessarily come up with on my own.
