Write.as/Writefreely vs. Draftin?
(Above: not my books, because I can't stack that high)
I'm very fond of both write.as and draftin. I'm not sure if they are in some sort of Venn relationship or a force dyad or something. There's significant overlap in some features and approaches, then very different things, and a smattering of areas where I wish they could join forces. (I think I'm imagining write.as as the container enveloping draftin, but it doesn't really matter.)
They both share strengths in making the getting words down easy, clean, and enjoyable. Draftin has this focus on version control and collaboration which is its particular strength. Write.as is more robust for the blogging model and the degree of customization with the blog output is in that goldilocks territory of just enough to make it enjoyable but not too much to be overwhelming or distracting. I really love that feature. (It's a solid feature of ghost too, incidentally, but that's yet another set of needs/audiences/workflows and a different answer to the “alternatives to wordpress” question.)
I like both a lot and neither is fully comfortable all the time. And that's ok.
