I often use epsilon in the same informal way AdeleneDawner does, though I'm perfectly aware of the formal use. Still, I think the informal use of "modulo" is more defensible - it maps more closely to the mathematical meaning of "ignoring this particular class of ways of being different"
Could you explain this in greater detail? This way of using "modulo" bothers me significantly, and I think it's because I either don't know about one of the ways "modulo" is used in math, or I have an insufficiently deep understanding of the one way I do know that it's used.
I would like to propose this as a thread for people to write in their predictions for the next year and the next decade, when practical with probabilities attached. I'll probably make some in the comments.
