In the episode, the runaway, do you remember Aang earthbending blind? That was cool, but then I thought,
"How will Aang use this blind earthbending to his advantage?" Will he use it later?

I pondered this thought, but came up with little. Maybe he could use it to detect sudden attacks? sneak attacks?

I think my theory will be shortlived, but in all the reviews I read, no one else mentioned it.

Do you people agree with me?
