One technique that many successful bloggers use to stand out from the crowd is to use images in their feeds. This means switching your feeds to full feeds, enabling html and putting up with a little more bandwidth but in my experience of surfing through thousands of posts a day in RSS it makes a big difference.
Images draw the eye, they pique interested, they grab attention and they have the potential to make what can otherwise be a dry and text filled environment (news readers) a more visually pleasing and sensual space.
