This isn’t really an exhaustive list. I’ll dig up some more and add them later or post in a separate post. Most of these authors I’m friends with or follow and Facebook and they cross post or link their blog articles to their Facebook pages. I really need to find more blogs about writing itself – the posts in these vary between promotion, cross-promotion, reviews (not just of books), and some politics (but I’ve omitted the ones who are mostly political).
Adam Troy-Castro is a novelist and short story writers who writes most SF and horror. He also writes book review columns. He has a huge Facebook following because he’s witty, opinionated, and likes to engage people in discussions. In fact, he posts occasionally to remind people who’ve followed him for other reasons that he is a professional writer. There are a lot of good, in-depth movie reviews here.
Steven Barnes is a writer I’ve been reading a long time, starting with his collaborations with Larry Niven and Jerry Pournelle in the 1980’s. He teaches Lifewriting seminars and writes a lot about life coaching, Afrofuturism, and martial arts.
John Scalzi is a hugely successful SF writer. He isn’t very active on Facebook, but is all over Twitter. His blog, Whatever, is extremely popular and often controversial. One of the cool things he does is to use his large audience to let others promote their books (look for the posts titled The Big Idea:)
Ari Marmell‘s blog, Mouseferatu, is mainly used to keep his readers up-to-date with what he’s working on. Ari has written for RPG games and has quite a few novels as well, including one of the funniest fantasy novels I’ve ever read, The Goblin Corps, and an urban fantasy series set in the 1930’s about a Fae detective named Mick Oberon. He has a Patreon which gives his supporters free stories, beta reads of chapters as they’re completed, and a few other perks.
Stephanie Osborne is a local Huntsville writer who is retired from NASA. Several of her books are small press published, including her latest series, the Displaced Detective, which are about Sherlock Holmes transported to the modern day United States. She’s also collaborated on several books with Baen authors, including Travis Taylor, another Huntsville native (and star of the show, Rocket City Rednecks).
As far as what I read online about the process of writing, I’d say it’s most often Reddit’s r/Writing or some of the other subreddits about fantasy and SF writing, reviewing, etc. Maybe that should be another blog post to go over the various writing subreddits.
John Picacio is a cool artist and an acquaintance of mine from a few conventions. I like his art (I have two framed prints of his at home and several of his Loteria series cards) and he’s a cool guy. I used his Loteria painting La Sirena as a partial inspiration for “The Rusalka’s Embrace” story I wrote recently.
