Adding Rolls

Rolls allow you to add list of blogs you are reading, your favorite links list etc. First one I came across was adding link-roll using del.icio.us. Delicious allows various customization to the list such number of links, tags to be included, include the tag names etc. The link-roll automatically takes the styles from your style sheet. Does not require CSS customization for making it similar in look and feel of your blog.
Popular choice for adding a list of blogs you read is through Blogroll. But every time you want to add a blog you got login to blogroll and the blog. There are no plugins like the once provided by delicious. I would have preferred the feed readers giving this choice. But recently Google reader has provided a better way of sharing the feed or blogs you are tracking. It allows you to add shared or starred list to web page or blog. This is better than the blogroll and it shows more meaningful content. blogroll is becoming a thing of past!
One of the most recent things I came across was TheGoodBlogs. This allows you to add a list of blogs which are relevant to your blogs. I have just added this to this blog and wait watch to see the relevancy of the blogs!
