If the rejection letter I just received is to be taken at face value, Philosophy and Social Criticism is currently experiencing a glut of papers devoted to Marx and Marxism.
UPDATE: For the record, the ratios of the number of articles on Marx and Marxism (NB: based on little more than a perusal of article titles) to the total number of articles published in Philosophy and Social Criticism over the last five years are as follows:
2004: 0/43
2005: 1/45
2006: 1/39
2007: 1/42
2008: 1/44
To be sure, my essay might suck, and P&SC has fulfilled their one article per year quota of Marx and Marxism for 2008.
