So, I've had a few people tell me that I should work on developing my platform as a writer, even though I haven't been published yet. I've been considering getting a Twitter (I don't use the site personally, but I've been told it's an essential for writers to get out there) but I'm not sure what I would tweet about, considering I don't have anything to promote yet. What types of things do you guys discuss on your writing social media platforms, aside from your own published work?
