If you use MarsEdit for Tumblr, you are undoubtedly frustrated by the recent collapse of support for the service. I’m frustrated, too. I’d like to say it’s all in my hands to fix things, but it isn’t that simple. I can make further concessions, removing features to adopt their V2 API. But doing that will take time, testing, and energy. With Tumblr, more energy than it should. It takes two to tango, and Tumblr doesn’t dance.
I do use MarsEdit for Tumblr and I am frustrated. Not the first time Tumblr has frustrated me and not the first time I've wondered why I don't just rely on Little Running Bear for all my blogging.
