You already know my feelings about that exploitive science publisher, Elsevier; I'm not the only one, and there's been a long, long history of anger over their publishing model — and it's not just scientists, but scholars in other disciplines who have been peeved.
Now a boycott has coalesced. If you publish, edit, or review Elsevier journal articles, make your opinion known and sign the petition.
