I would be happy if I never saw them. To say it is only courtesy to use them and it only takes one little mouse click to read them is bull.
They are annoying to many people, especially when overused as they are. They make it more difficult to read the threads. It is impossible to read the spoiled text using Feedreader. I am forced to launch a browser to read them.
Cthree, is it possible to have an option in your profile to ignore spoiler tags? That way, people like me can just turn them off and ignore this whole debate. Plus, it would fix the problem with Feedreader.
