MarsEdit is a blog editor from Ranchero Software. Since I use NetNewsWire as my
aggregator feedreader and like it, I thought I'd give it a go. This post is coming to you from MarsEdit.
The program is pretty straightforward. It integrates with Movabletype (and many other blogging tools) well and does a good job of saving and uploading posts. On the other hand, there don't seem to be that many advantages over using the Web form, except that you can do it offline. But then, I use Emacs for that. I don't think it will change how I work, but if you're looking for an offline editor for your blog, this might be a tool to try out.
