My first comment on the subject was based on an analysis from the outside, asking whether there was any real harm in the tags, and I didn't think there was. When directly polled, on the other hand, on the question of whether it was a good idea, from the point of view of a participant in the project, to tag so many articles, I came to the conclusion that it probably was not, on the grounds that it was not very useful to the project and did impose some minor costs.
