The HTML our ChickletChooser service would provide you is the following example:
<p><a href="http://fusion.google.com/add?feedurl=http://feeds.feedburner.com/MYFEEDADDRESS"> <img src="http://buttons.googlesyndication.com/fusion/add.gif" alt="Add to Google Reader or Homepage" width="104" height="17" /> </a> </p>
Assume your Blogger blog's address is http://myexcellentblog.blogspot.com. You would change the chicklet link code above to read as follows:
<p> <a href="http://fusion.google.com/add?feedurl=http://myexcellentblog.blogspot.com/feeds/posts/default"> <img src="http://buttons.googlesyndication.com/fusion/add.gif" alt="Add to Google Reader or Homepage" width="104" height="17" /> </a> </p>
But wait, you say. I thought this was the point - promote my feed so it gets used and I get all those lovely stats! (You said this with considerable urgency.) It still is the point, but since you're redirecting 100% of your traffic to FeedBurner, the FeedBurner feed will be used at all times. The thing is, if you ever decide to leave us, there will be no hard feelings, but more importantly none of your subscribers will be left high and dry, subscribed to a FeedBurner feed address you no longer use or possibly even deleted. By promoting your original feed link only, you make use of all of FeedBurner's features but make sure your subscribers stay with you, even if you leave FeedBurner.
To summarize: Redirect your feed, but retain your original address for the links you promote.
