Webster was a contributing editor and columnist for the Science Fiction and Fantasy Writers of America Bulletin and published a collection of those columns titled Anthropology 101: Reflections, Inspections and Dissections of SF Anthologies through Merry Blacksmith Press. His Bulletin column, "Anthropology 101", examines the history of science fiction and fantasy through classic anthologies and anthologists, frequently pairing books by different editors but also presenting two or more books by the same anthologist. The column has included multi-installment pieces on Frederik Pohl, Robert Silverberg, Harry Harrison and more recently, Terry Carr. In addition, he has co-wrote three Bulletin articles with Dr. Jerry Pournelle. He was also a frequent contributor to the "Curiosity" page of The Magazine of Fantasy & Science Fiction. He was the poetry editor and columnist for Helix SF, an online speculative fiction quarterly. After Helix SF ceased publication, he took his column, "Past Masters", to Jim Baen's Universe, and when that closed, to Eric Flint's Grantville Gazette. The "Past Masters" columns are retrospective appraisals of so-called "classic" science fiction and fantasy authors, and include extensive bibliographies. Some of the authors covered in the "Past Masters" series include Zenna Henderson, Fredric Brown, Edgar Pangborn, and Murray Leinster.
