The Nation has a blog called "J Street" (unrelated to the new Israel lobby group) and describes itself thusly:
That mythical street between L and K is a metaphor for all that should be in the nation’s capital but isn’t: voices marginalized or ignored, ideas too radical or unpopular for the mainstream, movements elided or dismissed.
According to the English alphabet, the letter J comes after the letter I and before the letter K. The "J Street" blog has been active since February of this year. Perhaps someone should tell The Nation.
