Keeping the commentlink on all templates

The commentlink has always troubled me, I’ve never understood why the link is made to disappear on single.php and some other templates.

Check the front-page of my site, https://DotNeil.com, and you should see a commentlink. However, if you click on the commentlink, it takes you through to a single.php page, and the commentlink vanishes. You’ll also notice that the browser port doesn’t skip down to the comment area.

Does anyone know how I can keep the commentlink on all templates, and how do I make the commentlink skip the browser port to the comments area of the respective post?
