raph: Indeed, most convincing, thanks. The IACREOT website is interesting in a perverse sort of way, the organisation seems to have once been a functional professional organisation now twisted by the drive for revenue. I feel much the same way about the ACM: I have a membership, but I refuse to endorse them. While good scientific work is done under the ACM umbrella, the typical price of ACM conferences is an outrage, and academically exclusionary, and I think academics should as far as possible see if they can do their work outside the ACM. Kent Pitman wrote an amusing polemic against the Communications of the ACM, but I can't find the link now.
Postscript: I found the Kent Pitman article, it was a comp.lang.lisp post. Rather nice polemic, and I basically agree; while I don't think it is practical for most computer science academics to boycott ACM conferences and journals, I do think awareness needs to be raised about what is wrong with the ACM today.
