I meant to read Algorithms of Oppression anyway, but having a reading group at work helped me get around to it. ICYMI Google search results reinforce racist, sexist, and other untrue objective mathiness. Being an information professional, the meat of Noble's argument wasn't new to me, but having a whole book on the topic from an LIS point of view is vital. Noble's scholarly perspective isn't the only aspect of herself she brings to the table. She is explicitly representing Black feminism, as well.
A main thrust of her argument is that the white heteropatriarchy isn't any better at serving up unbiased search engine rankings than it is at anything other than reinforcing the white male gaze everywhere it goes. For me, one of the most interesting ideas she raised is that there ought to be a public search engine--publicly funded, for the public good, etc. Presumably that would also mean open source, but I'm not sure she said that specifically.
I underlined, circled, and made notes on every page and tweeted a tweet or two. I'm reluctant to write more until I get to hear what my smartysmart coworkers have to say about the book.
