Live Writer does try to show the layout of your actual weblog, but its not doing that good a job with my web log. What I truly want to see is if it will provide better interaction with blogger servers than Marsedit. Over the past few days, Marsedit occassionaly refuses to post. I'm pretty sure its the blogger servers. If their was a problem with Marsedit, I'd assume it wouldn't post all the time, instead of being intermittent.
