Eu não sei de um produto semelhante com all dos recursos, mas O Blog do Gnome é bem legal. É muito simples de usar e funciona diretamente no painel:
Features:
- Clean interface doesn't get in the way of what you're writing
- WYSIWYG styled text support
- Entries can be written gradually over the course of a day, popping gnome blog open and closed as you have thoughts to jot down and then posting at the end of the day
- Operates as a panel object/applet or a standalone application
- Supports many different kinds of blogs
- New Spell checking
- New Drag and drop images into your blog entry (if your blog supports it)
Supported Blogs:
- Blogger.com / Blogspot.com
- Advogato.org
- Movable Type
- New WordPress
- New LiveJournal.com
- Pyblosxom
