I am starting to blog and choosing between Svbtle or Medium, now that both are in GA. Which do you enjoy better and why? Does Medium's network distribution rival Svbtle's? Is Medium's platform advantages outweigh not having your own custom domain?
I've been asking many ppl the same question. I would recommend considering how important authorship control vs content spreading. I've heard that Medium puts the author secondary and doesn't provide robust analytics. I haven't thoroughly tested Svbtle yet (about to). Ghost seems great but I don't want to host my own and debating if the price-point is worth it. I think it's great how much design innovation is going into the content creation process.
I wrote a blog post about this that you may find useful: <a href="http://blog.binarybalance.com.au/2013/12/06/why-i'm-not-writing-on-svbtle" rel="nofollow">http://blog.binarybalance.com.au/2013/12/06/why-i'm-not-writ...</a>
You might want to consider to add Ghost to the list of considerations as well. In terms of UX it's close to both Svbtle and Medium, but you get to keep your own data.
