If you’re a writer, and on Twitter, you should definitely be following Angela James. Whether you want to submit to Carina Press or not, she tweets a lot about useful publishing information. She also has some her tweet sessions on Storify. All of these I found very helpful: Ask Agent/Editor, Editor Report, Promo Items on Storify.
Then there’s this post which is a recap of an Author Branding session Ms. James gave at The Emerald City’s Writer Conference. This post is another recap of the same session but does offer some additional info.
