@DavidCT & Harriet
I mostly agree with you DavidCT, but I do not really see why impact factor would be such a quality mark regarding the demarcation problem. Unfortunately, there are too many pseudoscientific journals listed by ISI and “they” could possibly just cite each-other to raise the impact factor. I have no suggestion to the problem, but neither impact factor nor peer-review makes a journal immune to nonsense.
