I'm writing this post with the new Windows LiveWriter -- a WYSIWYG blogging tool. So far, I'm impressed. As much as I like Typepad, I've never liked the default post editor that much. On more than one occasion, I've lost a brilliantly written post because of a browser glitch. Eventually I got fed up and started writing all my long posts off-line. Word sucks for blogging, so I resorted to using Typepad, which is great for text editing, but mediocre for blogging.
Here's a trippy pic of this post being written within LiveWriter:
Kudos go to the Microsoft team that developed this great tool! (I hear its a really small team of 4 people, which is probably why it is so good).
