Not that it matters. When I first started this blog, it seemed that most blogwriters were using clever pseudonyms, and I assumed that was an obligatory aspect of the style. Some still do, some don't -- who cares?
"Bartleby the Scrivener" was and remains my favorite among Melville's works. I did not, however, put much thought into the choice. If I had, it might have occurred to me that "Bartleby" probably wouldn't be chosen as a nom de keyboard by more than a few million online scriveners. So it goes.
