Nadia Eghbal hates the term open source, which currently gets, let's see... a little over a quarter billion results in a Google search. YMMV, of course, but it's kind of a done thing.

She correctly notes that the term was born in a 1998 meeting of geeks. Though I wasn't at the meeting, I was one of the larger (but still small) circle of geeks who helped promulgate the term, and even got an award in 2005 for doing that. For those interested in my own take on what open source means, here's my chapter of an O'Reilly book on it. Holds up pretty well.
