I tagged two items today that I probably would not have tagged before:
Spoiler for Kurenai/Monster comparison with further spoiling commentary:

I could have avoided spoiling
Monster by writing this carefully and using references to "Steiner" throughout. That's not a very common situation, though. The announced policy seems to require that any such cross-content comparisons now need to be tagged as spoilers.
Here's an example of more "casual" spoilage from a posting in the Suggestions thread:
Spoiler about romance in Saiunkoku Monogatarai
I've written about SaiMono many times and probably expressed a similar observation outside tags from time to time. While I think I'm usually careful about spoilage, the announced policy has made me aware of casual spoilage examples like this one.
After consideration, I think both these items should be tagged. It actually made it easier to write both comments, especially the first.
