I'm just pointing out that the original comment was no more of a spoiler than the article all these comments are posting about. It would have been different if the post was pointing to the story, and someone dropped the Wikipedia article/spoiler in a comment there.
Hmm, well I knew what I did was not the best way, but I thought if I just linked the story, not many people would read the whole thing ! So I thought this was the best way to reach out to a larger audience, give them a summary of the story.
