Ease Your Blogging With Blogo
With Live Writer doing the things simple for Windows, Blogo does this for Mac. The first thing which you will notice after installing Blogo is its simple and attractive design.
The application makes posting text, images and multimedia content from the web easy for users with no knowledge of HTML.
Blogo’s strong points include a rich text editor with support for drag and drop of almost any image format and an HTML source view for manual adjustments, an automatically generated preview template which shows the user exactly how his post will appear when published, a fullscreen editing mode and support for comment moderation with the new WordPress comments API. Many more features.
Not only wordpress, it supports all types of blogging platforms. Blogger, Typepad, Typo, Drupal, Expression Engine, Twitter, Ping.fm and more
But the annoying feature is tat it is not free !!!!
