This whole long conversation about the tweets only reconfirms me in my position: if it is about the comic, and Rich says it, it does not matter if it is redundant with the comic itself, other quotes, or even contradictory of previous quotes, it should all be in. If it's not about the comic, it does not belong in.

I'm for the inclusion of the tweets. I was not confused, but given that people seem to have gained clarity from them, and they are about the comic, I feel they belong.

Of course, my view of the purpose of the index is not based in ease of use, but in exhaustive and rigorous documentation. But I recognize myself as part of a minority on that.
