Yes some interesting comment by Trillium. Where the articles mainly promotional? Yes very. A number of them were copied and pasted from press releases by the companies in question.
Were a number of the editors from the developing world? Also yes. This is because they are willing to work for less and Orangemody was hiring from sites like Elance.
I guess the fundamental question is, is Wikipedia a workspace to provide employment for those in the developing world who are willing to do PR piece work for some unknown PR firm? Or is Wikipedia an encyclopedia.
