I suppose, but they are only opening articles that are 70 years old. Which means curiosities like Darwin's geology papers are now available, but you still need to pay for anything remotely current. So it's a nice start, but unlikely to effect their bottom line, or make doing science any easier for anyone outside the first world academy.

Yes, you're right. But it's still a step in the right direction and hopefully others will follow suit. And I am really optimistic, looking at the uber-cool initiatives of the Khan Academy (http://www.khanacademy.org/), MIT's OpenCourseWare (http://ocw.mit.edu/index.htm), Stanford's OpenClassroom (http://openclassroom.stanford.edu/MainFolder/HomePage.php) and their latest online courses in Machine learning (http://ml-class.org), Artificial Intelligence (http://ai-class.com), and Databases (http://db-class.org).
