I like the idea especially if you are keen to set it up.
It may encourage others interested in cognitive science / psychology to get involved with the site. In particular, I imagine that people interested in discussing journal articles are the kinds of people we want more involved with our site.
Naturally, a number of questions arise:
- Is there sufficient interest?
- What journal articles should be reviewed? How would you select an article that is of interest to enough people given the breadth of cognitive sciences, psychology, etc?
- What format should the discussion take?
- How could participation be sought from outside the typical user base of cogsci.se?
With regards to interest, I imagine that it would be worth an experiment at least once to see what kind of uptake there is.
With regards to format, just my opinion, but I think it would be great if the discussion interfaced with the site itself. One of the reasons that I participate on this site is that it leaves a legacy for others on the internet. I think it would be great if perhaps the discussion might generate some question-answer combinations on the main site.
In terms of seeking participation, perhaps this might be an exercise, we could more readily ask our colleagues to be involved with or ask users of other cognitive science / psychology sites whether they would like to participate.
