The Politics Of Citation
Discussions on both topics frame citation as a duty owed to the idea-originator. Inserting links or references may be burdensome, the thinking goes, but you have an obligation to direct attention and credit toward those whose ideas you've used. This is a good way of thinking, and it helps us set a baseline minimum level of citation. And it explains the anger of those making the failure-to-cite charge.
But I think it's incomplete if we don't also recognize that citation makes what you write better. Your work becomes not just a thing on its own, but a portal to a larger discussion. Right now I have a 19-page, single-spaced 10-point document listing articles and books I want to read. The vast majority of this document was compiled from reading other articles and books, and making a note of the source whenever the author referenced an interesting point. I get annoyed sometimes reading things written for less formal publications that are looser about citation -- "you just said something interesting, I want to know where to read more about it!"
So when I read Farrell's question, I approached it not from the perspective of a writer wondering if he had to go look up the links and format the citation right, but of a reader who might find a full citation useful in tracking down the source of the idea and reading it in full and in context. And when I thought about the Marcotte controversy, among my thoughts was how a layout a bit more like Sylvia/M's version would have been a better article -- Marcotte obviously couldn't cram every idea brownfemipower and other bloggers of color have had on the topic into a single article, so citations would allow readers to see the fuller discussion (about the substantive issue and about the pedigree of the particular way of understanding it). I suppose it's symptomatic of a larger attitudinal issue -- is coalition-building something you do because it's necessary to allow you to get on with pursuing your own goals, or is it something you're excited to do because it enhances what you're doing? (To allow my tired brain to roam perhaps too far afield, I'm now reminded of the distinction made by some Christians -- exactly who I can't remember because it's been so long since I thought in these terms -- between framing the message as "Jesus died for you, so you owe him big" and "Jesus loves you, how does that inspire you to live?")
*As an aside, why is it that Hugo seems to be unable to link to women of color except to defend white feminists against funhouse mirror versions of their criticisms?
