Here are six startups that offer new options to creators. Three of them — Periodical, 29th Street Publishing and Creatavist — let you create and sell mobile-friendly magazines, ebooks and newsletters; the other three — Postach.io, Ghost and Glipho — aim to let you blog in a new way.

All of the companies featured here launched in the past few months (or, in Ghost’s case, will launch later this summer), so they’re still working out some quirks and rolling out new features. What they have in common, though, is that they’re all trying to make writing and publishing easier and better. Check them out and let us know what you think (and which startups we should add to our list).
