I don't know what this is, but it looks really cool. Also, the survey meme things will stop when I start going to school and having a life again, I promise.

The surveys don't bother me...it's just that it seems like nobody posts not-surveys anymore, which is a little sad.

OR is just like if I said "Do you have a pen or pencil on you?" And you have either, the answer is yes, and if you have both, the answer is yes.

Note language is ambiguous, and not every instance of the word 'or' is similar to the strict logic definition of OR.

XOR is just something that specifically asks if you have a pen or a pencil, but it is false if you have both. It is like asking: do you have specifically one of the following two choices?
