In the "send an email, post a blog entry" fun and fast-paced world of tomorrow, services like Tumblr and Posterous make it exceedingly simple to prepare and post to your blog; meanwhile, Twitter, Facebook and AOL Lifestream push past the article metaphor to 140-character status snippets. Delightful as they all may be, sometimes it's nice to have a well-rounded Mac app that supports more reflective and considerate writing for your online outlets -- not to mention one that saves your drafts in case your browser picks that particular moment to crash.
For a lot of bloggers, including many TUAW veterans, Red Sweater's MarsEdit (US$39.95) is that app. It allows you to write, edit and schedule posts offline at leisure, with full preview capability so you know what you're getting when you hit the Publish button. It will happily upload your images and files alongside your posts, and it works with scores of popular and obscure blog back-end systems (WordPress, TypePad, Tumblr, Squarespace, etc.). If you prefer to edit elsewhere but still want the uploading savvy MarsEdit delivers, it plays nicely (via the ODBEditor scritping suite) with other text editors like SubEthaEdit and TextMate.
MarsEdit has just hit version 3.0. At long last, WYSIWIG rich text editing is included, alongside the traditional HTML/text edit window that has cheered experts but may have intimidated novices. Other new features include better syntax highlighting in HTML, support for WordPress static pages, media browsing from iPhoto/Aperture/Lightroom libraries, and more.
You can download a 30-day trial of MarsEdit and see for yourself if it works the way you do. Upgrades for previous owners are free if you bought MarsEdit in 2010, and $14.95 for all earlier purchasers.
