Blogging Tutorial - Adding a Home button

I thought I didn’t need  home button, but I was wrong.  If someone follows a link to your page, that’s all they will see, that page, and they won't see your latest posts, can they judge your blog on that?  Some of our posts are better than others, what if it’s an iffy one, they may decide not to link up again.  Yes, they can look at your previous posts in your sidebar, but not everyone will, do you?
