The point of tagging is that it groups those threads you put that tag on so you can find those posts easily again. Click on the word Tags and type in "testing" without the quotes and this thread and three other about "testing" come up.

Perhaps for this site's purposes the tag "section" could be controllable in one's profile (or on the page) so it could be turned off, like one can click the arrows for whole forums and only concentrate on what one wishes to? That way people who do not wish to use tags or are disturbed by them could just "ignore" them.
