You can blog to Tumblr with myTumblr, a full-featured blogging client from MOApp Software Manufactory built just for Tumblr, entirely from the keyboard. A series of shortcuts let you pick which type of post you want to start (ex: Command+1 for Text, Command+5 for Link), and you can tab through all the fields like tags and the body of your post. When you’re done, Command+Shift+D ships the post off to Tumblr, just like it sends a message in Mail.
