Well... fake ones!! A great addition to Blogger Hacks: The Series that fills another frequently requested formatting gap on blogger. Johan at Ecmanaut has written a post describing how to add "next" and "previous" buttons to each post of your blog. They're not quite next & previous post buttons. They're actually links that navigate your archives by day, and the system is not perfect by any means, requiring a 100% site republish on every day that you post anything. Still... if Next / Previous links are what you've been missing, this is as close as you can currently get w/ Blogger.
