Every once in a while I'll write something that could have been a blog entry (if I kept a blog), or something that is about one or more of my works, at the request of the publisher, or something that isn't published elsewhere but could be published here.  So I'll list them here as they arrive; it won't be very often, though, because I'm usually working on stuff that pays the bills, like a novel (or writing e-mails; when they get long, I start calling them e-pistles).  I'm not really sure they belong here; they're definitely non-fiction, but they're not print books, nor are they E-books.  This will work for now.
