I added what I think is a very useful feature to my blogs at the bottom of my posts called link within. In reading other's blogs I came across links with little thumbnail pictures at the bottom of their posts that suggest other posts written by them that are related. I thought that was a nice feature and found myself reading more on their blog that way so decided to add that feature to my blogs too. It was easy to add (unlike "commentLuv"), but it takes a day or two for it to work because it has to have time to "crawl" the blog.
I hope you will enjoy this new feature and maybe consider using it on your blog as well. All you need to do is click on "related stories by link within" found under the thumbnails and it gives simple instructions to follow for adding this cool feature to your blog. I'd like to know what you think of it, especially if it encourages you to read additional posts.
