This is a great subject for discussion. It seems like there has to be an amount of time that's reasonable, rather than warning for spoilers for everything, forever. Mainstream media doesn't care, so it's easy to get spoiled just by reading an article or seeing a headline.

And what exactly is considered a spoiler? Is my Torchwood icon above one? The show aired in 2008, but those who haven't watched it might not know Jack and Ianto got together. I have another icon I want to use, but I worry it's a spoiler, so I'm still waiting. That show is only a couple of years old. Sometimes I come across comments about shows while browsing social media. They aren't even shows I plan on watching, but I already know things about them just through fandom osmosis.

See now I'm worried I've spoiled someone by pointing out my Torchwood icon...
