MarsEdit 2.3, which was released on Tuesday now supports Tumblr, in addition to WordPress, Movable Type, LiveJournal and other blogging platforms. Daniel Jalkut, the developer of MarsEdit, announced that he was planning support for Tumblr back in December, after started working with Tumblr's Marco Arment on improving the Tumblr API.
After a brief beta period, official Tumblr support is finally here, and it is good. To my knowledge, MarsEdit is the only blog client, for Mac or Windows, that supports Tumblr. Sure, there are some great iPhone (and even a BlackBerry application), but there hasn't been any support for an actual desktop client.
Inevitably, some users will question why Tumblr needs client support at all. After all, isn't the whole point of Tumblr to be fast, easy and simple? Sure, but when composing longer entries or when you want to write drafts, an external client is still superior. There's nothing worse than having all of your hard work erased by a misbehaving web browser, or wanting to access a draft or an old post while on a plane or some other place without Internet access.
MarsEdit 2.3 supports text, photo, quote, link and chat post templates (though you can easily use HTML to embed video and audio in a regular text post). You can also easily add tags to a post. Image posting is extremely easy, just drag an image from the web, your own library or a folder into the image button at the top of the post.
If I had any real request, it would be that the "tweet this post" toggle be included as a MarsEdit option. Otherwise, my Tumblr needs have been addressed.
MarsEdit 2.3 is a free upgrade for existing users and news users can snag a copy for $29.95. It requires Mac OS X 10.4 or 10.5.
