This is as much for my own reference as anything else, but hopefully others will find this catchall useful. Another really fantastic resource for keeping up with the writing community on Twitter is Free Writing Events, who post daily with a roundup of writing tags. They also have a great calendar of writing events and contests on their website.

If you notice a resource or tag missing, let me know!
