Digging around for some papers on network growth models, I ran across a preprint of a paper by Michael Mitzenmacher scheduled for the new journal Internet Mathematics. Fan Chung (Graham?) is the managing editor of a seriously kick ass editorial board.
By the way, if you really want to understand the literature (across a number of fields) regarding growth models that generate power law distributions, you'll want to read Mitzenmacher's brief history of the area. It's not too hard to find using Google.
And of course it figures that the essence of the model was presented in 1955 by (Herb?) Simon. There really isn't much new in computer science.
Correction: I know think it's just Fan Chung and the journal web page has a typo.
Mystery solved. Chauvinist that I am, I didn't think that it might have been a woman with a professional and a married name. Mae culpa. I'll just leave it at Chung though.
