I’m writing this from Post2Blog - a desktop blogging client for Windows. Up until now it’s retailed at $39 a copy but has recently gone freeware. Using a desktop application to post to your blog can be a real time saver and gives a lot more control over the content. Here’s a features list;

• WYSIWYG (what-you-see-is-what-you-get) editor with complete hot-keys support
• Built-in "Live" spellchecking (check screenshot)
• "Portable Mode" support (check instruction)
• Images are uploaded automatically (supported uploading types: Flickr (see example), file area of your blog, imageshack.us, picturelli.com, custom FTP server)
• Post text and/or images from Firefox or Internet Explorer to your blog with 2 clicks only using plugins for Firefox (check example) and Internet Explorer (check example)
• Compose new posts in MS Word and post them to your blog using Post2Blog toolbar for MS Word
• Integration with RSS Bandit (rssbandit.org) and Sharp Reader (sharpreader.net) - you can post selected items from these RSS readers using Post2Blog plugin
• Post files, images, documents from Explorer or any other program using "Send To -> Post2Blog" command
• Add Technorati, Del.icio.us, Buzzwords, 43 Things tags to your posts
• Automatically send trackbacks, ping web-services to notify about updates in your blogs
• Earn money using "Insert Amazon Link" feature
• Use built-in smiles for use in your blog.
