I'm a member of the AAAS, in part because I support their various efforts, and in part because I like my subscription to Science. However, at least three times a year, I get junk mail at my house or at my departmental address, asking me if I'd like to join AAAS for the low new-member rate of $99/yr. How can these geniuses not realize that I'm already a member? I have an unusual last name, and they already have both my work and home addresses on file. Can't they tell that Prof. Douglas Natelson and Mr. Douglas Natelson with identical addresses are the same person? They must waste hundreds of dollars in postage and thousands of pieces of paper doing this, since I'm sure I'm not the only one getting these useless mailings. Good grief, folks, just do a sensible search on your mailing database for duplicates.
