It probably sounds disingenuous of me to say this, but when I sat down to write a post about Elsevier I wasn’t really trying to start a campaign. My intention was merely to make public, and a little more rigid, a policy that I and many others had already been applying, in my case without much difficulty, for several years. The idea of setting up a website occurred to me as I was writing the post: I considered it (and still consider it) not as a petition to Elsevier to change its ways — since I don’t believe there is any realistic chance of that — but as a simple way to bring out into the open all the private boycotts and semi-boycotts that were going on, and thereby to encourage others to do the same.
By accident, the post seems to have been quite well timed. Probably it’s not an accident at all, and that whatever atmosphere it was that prompted me to get round to writing the post (for example, certain discussions I had had with other mathematicians, some of them online) was the same as what made it a good moment. Anyhow, accident or no, the result is that some people have talked about “momentum”, and I’m starting to feel a responsibility, not particularly welcome (because it threatens to involve work), not to squander that momentum.
