I was looking for a desktop blogging software and stumbled across (yes, I stumble a lot) Windows Live Writer. Its pretty cool in the sense that it works well with Wordpress and actually downloads your blogs style sheets and lets you edit the post in a format as it would appear on your web blog. WYSIWYG.
It lets you preview and edit your post in several different layouts, drag and drop image support, spell checker and a few basic HTML editing tools.
Its pretty cool, I think I am going to stick with it for a while.
Happy Blogging!
