Saw this new dealy called WriteToMyBlog on Lifehacker. You can use it to post to all of the major services. It has a lot more functionality in the WYSIWYG department, including
strikethrough, Paste as plain text, Insert/edit anchor, Clean up messy html, subscript, superscript, €ð¡ (insert special character), tags, trackbacks and major table editing.
It's sparkly! It's new! I like it!
