A cross-platform (Linux, Mac, Windows), standalone blogging application that makes authoring and publishing your weblogs almost effortless. Unlike most blogging solutions, Thingamablog does NOT require a third-party blogging host, a cgi/php enabled web host, or a MySQL database. In fact, all you need to setup, and manage, a blog with Thingamablog is FTP, SFTP, or network access to a web server.
With PixelPumper, you can now create, edit and publish your blog posts directly from OS X in a beautiful retina display interface. It doesn't matter if you host your blog on WordPress.com or self-host, PixelPumper allows you to post to either.
Just like Live Writer helps you update your WordPress blogs easily while still being inside your desktop environment and not opening the browser. The app is available for free in the Mac App Store and measures only about 4.8 MB in size.
