This is old news but I thought I will write a small post informing about this new feature in Blogger for the benefit of those who may not know about it. Even if you burn your Blogger feed to Feedburner, some percentage of your visitors may still be reading the Blogger feed. This could happen if they had provided your blog URL (instead of your feedburner feed) to their feed reader and their feed reader auto-discovered Blogger feed. The side effect of this is that your subscriber count will not be accurate.
The first useful development of Google buying Feedburner happens to be the new "Feed redirection" feature. Using this, you can redirect your Blogger feed to Feedburner feed. You can do this by going to Settings->Site Feed and providing your feedburner feed URL for redirection (as shown below).
I did this sometime back and my subscriber count increased from 700+ to 800+ the next day. You could try this too!
Bonus news: Amit informs us of another new feature - Comment Form message with which you can show a message in the Blogger comments page. I made use of it immediately!
