I've been complaining about the blogger online blog editor forever. Today I took Windows Live Writer out for a spin and I like it. It's free, and it works with blogger without a hitch. My favorite feature is its preview pane which shows an actual preview of your post in the blog, which the blogger editor doesn't do at all.
In my heart of hearts I’ve always believe a rich client application should be more powerful then web applications, and in this case it is.
