It seems to have started about here at SVPoW:
Then it continued on talking about Nature and Elsevier
This was followed but a not really rebutal but reanalysis over at The Open Source Paleontologist:
And a response to the last post is available back at SVPoW
Whether you agree with them or not this is a very important issue. Especially as scientists become more global and journals should become easier to access. I know on campus I don't have as much problems as many scientists since my school provides me access to many journals that would be cost prohibitive if I did not have this access. Individual journal articles often cost $30-50 which is beyond absurd, and that's even before you know if that article has any content worth while to read. I believe this is something we can work towards, or at least make the current policies a little better.
Mike at SVPoW sums it up best:
"In the long term it is, unquestionably, to the advantage of all authors for open access to become ubiquitous."
