  Over the last decade, the set theorist Joel Hamkins has been arguing for a conception of set theory which bears a surprising resemblance to the traditional Skolemite position (though Hamkins' own motivations seem to come more from set theory itself than from the traditional philosophical literature).  Hamkins notes that, as set theorists have developed more and more powerful tools for constructing and comparing different models of set theory—forcing, inner model theory, large cardinal embeddings, etc.—they have become less and less likely to treat any particular model as cannonical.  Instead, set theory has increasing come to focus on comparing different models of set theory, rather than singling out one model as priviledged.  Hamkins argues, therefore, that set theorists should accept what he calls a “multiverse” conception of set theory—a conception in which no model of set theory is privileged, and the purpose of set theory is simply to explore the relations between the various models.
