Vaughan Simons managed and edited Writers' Bloc for the past year and a half and now it's gone, no new updates. There are a lot of wonderful articles archived. You can read them while they last, here.
In Simon's last post on Writer's Bloc he opened up with "After eighteen months online and some seventy-four articles, stories, interviews, flash fictions, poems and miscellaneous other forms, I’ve decided to close Writers’ Bloc. I feel that it’s run its course and, to be brutally honest, I no longer possess the enthusiasm required to keep it running, reading submissions and putting up new material."
Near the end of the post he said, "The domain name and hosting for Writers’ Bloc both expire in December. Whether or not I pay to keep the site online after that remains to be seen."
