Even though we can't use a tool like MarsEdit to post here at TUAW, some of us are still big fans of the program and use it when creating content for our other, more personal sites. Like Ecto, another very good tool for this type of content creation, Mars Edit allows you to compose blog entries, complete with text, links, photos or whatever, on your own computer and once finished, post them directly to your blog.
Of course, we're not the only fans of MarsEdit using it to put up content around the internets. Shawn Blanc, writer, Mac guy, drummer, Tae-Qwon-Do blackbelt and enthusiastic Mars Edit user has posted a very in-depth review of the application at his site. Among the program's many virtues, Blanc praises it for having a "perfect preview" of draft content, that it functions very well as a text editor and the "blatant absence of a WYSIWYG feature" which makes him "extremely impressed with how well it serves the writer."
MarsEdit 2 may not be the right choice for your blogging needs, but if you've never considered it before, this review might just make you want to give it a try. It's $29.95 for a new license, and $9.95 for an upgrade from ME1.
