I signed up, it's pretty cool. There are about 4-5 articles per issue. I'm still looking for one with a title I can parse, but this looks like a great resource. I've already marked down Pasadena in July '09 for the AI conference!

It's too bad issues 1-71 aren't available. I was really interested in comparing the content from the earliest ones with the latest ones.

Agreed. I had some hope that earlier issues could give me some perspective on the progress of AI research.

I do believe that this is a move in the right direction but, why require registration at all?

Maybe it's an attempt to limit 'I can has lolcats'

Does anyone know about any other scientific journals with free access?

lots: http://www.doaj.org/

cool i signed up how do i get the material, emailed to me?

this is awesome :D

Wow is that site ugly. Hopefully in return for free access to the content, someone gives them free access to a graphic designer.
