Citing Wikipedia articles in a physics paper should definitively give some points in Baez' famous evaluation scale[1]. On a first quick look the author at least refrained from (or was stopped) adding his insights to Wikipedia.
Interestingly some new papers have started using physicist's blog entries as references. But at least that's stuff, not everybody can edit.
BTW, http://arxiv.org/abs/quant-ph/0512053 is another example with heavy Wikipedia citing.
