A human friendly way to think of the logic gates
A more human friendly way to think of the gates function is to imagine that every gate asks the input(s) a specific question based on how the gates are built, the resulting answer is the output and is always a yes/no (on/off) answer. Here are some examples:

(feel free to improve/extend the list, or use it in the article if it's good enough, or use it as you see fit) --Sebbes333 01:50, 13 November 2012 (UTC)
 * I like this. I could see this in the introduction as sort of an alternate TOC. But I would put the question first, with the logic gate as the answer:
 * {| class="wikitable"

! Question ! Answered By
 * Is the input off?
 * NOT Gate
 * Are both inputs on?
 * AND Gate
 * Is either input off?
 * NAND Gate
 * Is either input on?
 * OR Gate
 * Are both inputs off?
 * NOR Gate
 * Are both inputs different?
 * XOR Gate
 * Are both inputs equal?
 * XNOR Gate
 * }

 * I have been thinking about what kind of questions eg. a RSNOR latch and other circuits asks, but as of now I don't know.
 * Anny suggestions?

 * An RS NOR Latch asks "Has input S turned on more recently than input R?". A T Flip-Flop asks "Has input T turned on an odd number of times?". --Munin295 20:29, 13 November 2012 (UTC)
 * Nothing to contribute just now, but I wanted to say that I like this approach! Now I'm wondering about D latches and D flip-flops.... --Mental Mouse 22:31, 13 November 2012 (UTC)

Input redstone / tables
I would argue that the input redstone of XOR designs C, E and J shouldn't be counted (reducing the redstone count of them to 12, 10, and 7 respectively) as it isn't counted for the other designs. There are probably other cases in the rest of the gates, but I wasn't looking at those very closely. Though, on design J the necessity of those blocks of redstone can vary depending on how power is being routed in from previous gates.

I also made this table for resource cost, but I'm not certain if it would be useful enough to add to the article.

Total costs of each design, not counting regular structure blocks:
