I follow a few writers who post on Twitter, very low key. They have regular posts from WIPs with #midweeksentence or #booksthatinspiredme, links to helpful articles on writing. They follow other writers, book clubs, publishers and reviewers so those are the people who will read their tweets.
No idea if it helps with marketing. I like looking at their writing sheds, lines from their work, their cats and links.
No no no @Quillwitch I don't write porn!!!! I'm talking about twitter pitch events such as #pirmad where agents like your tweet as an invitation to submit - and several times I've been all excited when someone has liked my tweet - only to discover when I go to their profile that they're, err, not an agent!
LOL! That's cheered up my Saturday! Kitty, you don't have to justify your work to anyone, okay? Just send it out in discreet packaging please, for your readers' convenience....
I've done SFFPIT before. Have had a couple of legit hits from them. I actually find them fun. And I find it curious how different pitches are received--gives you a feel for what agents are after. When I've done them, I've written about a dozen different pitches, each one emphasising a slightly different aspect of the story--plot, characters, theme, etc. Equally interesting is looking at others' pitches to see how they do.
There are some really good ones. It´s pretty quiet though.It's really interesting reading through the tweets on the #tellAMH feed on twitter. Especially seeing what the agents are liking! Definitely gives you a feel for what's hot right now in the crime thriller genre
