BlogBaboon is a desktop client for editing and publishing posts on your Blogger blog.

Instead of Blogger's HTML or WYSYWIG input, you get to use lightweight wiki markup.

Instead of Blogger's unconvincing preview, you get to see exactly how your post will look.

BlogBaboon may suit you if:

• You write long thought-out pieces that generally take days to write and revise.
• Code snippets and the like are common enough that having to manually HTML-escape is annoying.
• You believe that lightweight markup is superior to any attempt at WYSIWYG you've ever used.
• You sometimes find it hard to see your post through all the heavyweight HTML markup.

BlogBaboon may not suit you if:

• You like editing HMTL or like Blogger's WYSIWYG interface. (If you're happy, stick with it!)
• You like WYSYWIG editing, but not Blogger's implementation. (Try something like Google Sites or Writely?)
• You write very short posts. (Try Twitter, or stick with the blogger.com web interface?)
