I wrote the previous post using a tool called Kung-Log, written by a fellow Dutch person. It allows me to write blog posts in an application instead of a browser. Which gives me advanced functionality such as, ah, undo (which Safari's text editing field does not provide), but more amazingly, HTML shortcuts, meaning I never have to type <a href="" target="_blank"></a> ever again. So far, I'm quite happy with it.
Update: It even allows me to go back and edit entries I've already posted.
