Many years ago I added a feature onto TYWKIWDBI, created by LinkWithin. It added several images at the bottom of each post linking to previous content on the blog. I thought it was a useful feature, and from the metrics I was able to monitor, it seemed to be used extensively by readers to explore random old posts.
Now it seems to have disappeared - without warning or explanation. So this question for other bloggers: is this feature available outside the Blogger system under a different name, or are there other equivalent add-ons I could add to my blog's template?
