The UPA have just launched a new international peer-reviewed journal, the Journal of Usability Studies (JUS, or Juice as I reckon it will be referred to).
The first issue seems to be freely browsable, I wonder how long that will last? (-; It includes an invited article by Jakob Nielsen, who asks how the usability community can scale to support the millions of interactive systems being developed today. He offers 2 possibilities: (1) train a million usability professionals (picture useit.com running courses in the Astrodome), or (2) improved discount usability methods, easily accessible to designers etc. (1) is frankly terrifying to both non-Usability and Usability people. (2) is frankly terrifying to Usability people. So I guess (2) wins out.
