Did I miss a discussion about this new tag, event-based-effects? I am not sure it should be a tag (it smells a bit meta, like "homework" or "urgent") but if it should, perhaps current-events or temporary-situation would be better. I could not figure out what it meant from the tag name alone, nor the wiki excerpt really. Seeing what it's applied to, we might need it, but I would like it to have a different name.
Late January 2014: This tag is still here and still being used. We need to tag Ukraine questions with something at the moment, but I still do not like this name. I would like to see either "temporary" or "rapidly changing" in the name I think. Well, "temporally specific" would be better, but some people might think I was mis-spelling temporarily.
