There are some popular blogs like daring fireball, the loop or marco.org which use the so-called linked-list blog style where the headline links go to external URL instead of the post’s permalink. The post itself usually consists of a quote and a comment on it by the blog author. In my opinion linked lists are a reader-friendly way of posting links to interesting external resources.
In Jekyll, linked-list style posts are not possible out of the box. It is very easy to implement this feature though. This post’s headline links to a GitHub repository in which you can find instructions and example code. To open this posts permalink instead, just click the infinity sign in the meta data line.
