This is also going to be good for science fiction writers. A ton of the time I want to check facts and all the authoritative sources are behind paywalls and would cost me more to access than I'd get paid for the story.

It'll help us get stuff right.

As a note, however, if you really need access to a paywalled article, often you can contact the authors directly. They don't get a penny from those paywalls and are typically glad to send you a copy. It's an extra step, though.
