I only subscribe to two twitter feeds: Jim Butcher’s, though he doesn’t tweet much, and Daily Writing Tips. But you can go to the website and see all the great tips. Normally, it’s sort of like Grammer Girl with larger lung capacity. But occasionally you’ll see stuff related to crafting, like his article: Let the Words Do the Work.
