So this post is being completely written using the new Windows Live Writer. So far? I'm impressed. I'm exclusively on my mac at home & prefer MarsEdit for day to day blog posting there, but I could definitely get used to using Live Writer for while I am here at work. Testing insertion of picture....ok....it looks like Live Writer adequately plugs into the WordPress API and supports all of the features I require: categories, tagging, uploading images to wordpress, &tc &tc. I actually like this a lot. Now only if Microsoft would make a Mac compatible version & this could one day supplant my MarsEdit usage on my Mac.
