Google has released the new Feedburner with Google Account access and easy migration (redirect) for Blogger. I just added my feed. I wanted to go with Feedburner earlier to get statistics, which Blogger itself never offered, but since it before required me to change the feed URL I wanted to keep my current subscribers at the current URL. Now you can enter a URL for the feed to be redirected to in Blogger. You will find it under 'Site feed' in your Blogger settings. Enter the URL Feedburner gives you after signing up your blogger feed.
