Custom Blog Home Archive?

Hello.

I am a noob ?? I have a menu link to my blog home page that shows the archive of all my blog posts. Visitors can see the entire blog, yet for some reason they have to click on the blog title to be linked to new page that has a comments box and sharing options.

Is there a way (plugin maybe), that I can have the comments box and sharing buttons on the archived blog home page? Or is there something I am missing….for example should I be using a different option for my menu blog link?

Any tips I would greatly appreciate! Thanx!
