I noticed that Chris posted in my Spoilerful Infinity War conversation (seriously, SPOILER WARNING) to say "Now I HAVE to go". Whoa! That's a deep end of the spoiler-pool to jump into on purpose!
But then, people are VERY different about spoilers. I don't like them myself, and have often been careless and spoiled something for someone else, so I now try to exercise Extreme Spoiler Hygiene, to avoid removing someone else's choice in the matter.
However, I realize my own spoiler aversion is partly irrational! There was that study that indicated spoilers increase enjoyment. And in my own life, I've still enjoyed stories that have been MONSTROUSLY spoiled for me. For some reason I listened to Terry Gross interview David Simon about just about every important death on The Wire before deciding 'maybe I WILL watch this show!' and turning it off: while I wish I hadn't known about them, I still loved the show. One of the most famous (and oft-parodied) quotes from Jane Eyre is sort of incredibly spoilery, and I knew big chunks of its plot as well before I finally read it at age ~35. And yet it still surprised me, and I really enjoyed it.
I really enjoy the one of my close friends who prefers to have spoilers -- I can discuss just about ANYTHING with him with wild abandon -- but I also don't understand that response. Despite all of the above, I just HATE spoilers with an irrational, visceral hatred. I'll continue to spoiler-warn for, say, spoilers about the end of 20-year-old TV shows, and I'll continue to banish the Star Wars alphabet book with the offending letter L to the basement rather than giving it to any kid to read. It's irrational, but it's how I am!
