Hello strange people: by way of introduction, I am Dan Ritter, occasionally seen in the comments section as -dsr-. I live outside of Boston and work in Cambridge, doing various bits of computer work just off of the MIT campus for a small financial software firm -- if you don't work for a bank or brokerage, you probably haven't heard of it.
I once suggested to Charlie that since the Indian Navy was having budget problems, they might agree to sell a de-militarized Krivak-class frigate, which would make an excellent evil billionaire's yacht.
Today my subject is "free SF", by which I mean stories that you don't have to pay money to read. That doesn't necessarily mean that they are in the public domain, or that the author has given up copyright; it just means free of required monetary cost. Some authors do that as a sort of advertisement for their work; some do it because it makes them happy, some do it because they don't want to put it up for sale (or can't -- that's a whole class), and some are doing it for the exposure so that they can build an audience. All of this is only viable because the Internet has such a low marginal cost. For me, the best thing about free SF is that I have a zero-risk opportunity to read new authors, and the second best thing is that I have more money to buy books.
