A feed burner icon today is very common in sites with most of them being blogs.Some of the blogs offer subscription to blog's XML feed via Email.What about those who don't?
Many people, like me, are too lazy to check in their Google Reader everyday where I had subscribed the feeds of my dailies. How about a rotating headline right inside your G mail In box where you commonly see some sponsored links and some latest headlines from news blogs.

I recommend that you do not use the feedburner feed url as it not always works
