I don't want to sound like a douche, but It looks to me that you did it to prove you eat your own dogfood. If you were so unhappy with Tumblr, why didn't you just use another blogging platform or software? There are many alternatives in almost every language known to man.

Because of the reasons in the post, but mainly our design team. I didn't want to set up a WordPress instance and make them learn the intricacies of php and WP theme system. They already understand the Rails folder structure, Sass, Haml and all the other tools we use.

tl;dr: it made collaboration easier.

I'm going to agree on your point as well. Designing with things like WordPress, Tumblr, etc become a major pain quickly. Especially considering the speed at which you can design with a bare rails app.
