If you have a Blogger blog, consider using BlogThis! to quickly and easily post entries.
BlogThis! provides an interface for posting entries to your blog without visiting Blogger.com. After you add a BlogThis! link to your browser’s toolbar, you can click on BlogThis! to add a link to the web page you are visiting and also include any text that you highlight on the page. After adding any other text you want to include, you can then publish your entry or save it as a draft.
