I saw that earlier today. I'm about to take advantage of a free year of Ghost, so I'm not biting.
There seems to be a strong hatred of WordPress these days, and I really don't understand it. I get people want a cleaner space to write in, but it's easy enough to do that with most writing apps out at the moment. Why not keep the really robust and secure backend, and just use your preferred app? It is easier to go download a gallery plugin within the admin, then it is to code one in with the layout and then have to include the extra attributes overtime you post with these other services.
I like writing, but sometimes I like posting a couple of images and don't necessarily want them in the essay style.
