In a recent meta post about the symbolism tag, Rand makes the point that way the tag is currently being used is very broad:
... but we've been using symbolism in a very broad way.
Our questions tagged with symbolism include not only ones about symbolic objects (e.g. What does the sukebind represent? or What is the greater meaning of the thrush?) but also ones about symbolism on a wider scale: symbolism of actions, events, or even entire works, such as What is the significance of the fact that the covered wagons were traveling East at the end of Atlas Shrugged? or Is there any deeper significance to Borges's "The South"? or What's the significance of the witches' name change in Sandman?
There were some recent comments about this sort of issue between myself, Hamlet, and DVK on one of my questions, but they seem to have been deleted. If I recall correctly, Hamlet was arguing that "symbolism" should only refer to symbolic objects and not to actions or events. But the usage so far of the symbolism tag (our most used tag!) tells a different story.
I personally find that (1) the symbolism tag doesn't have a clear purpose, and (2) as a result it gets applied inconsistently. This makes it worthless as it's 50/50 odds that a question tagged symbolism has been tagged correctly.
When should questions be tagged with the symbolism tag? What purpose should this tag have on this site?
