How to See the Blog 'Timeline' in MU directory sites?

Right now I have a few blogs installed in directories on my MU (with Wordpress 3.1.1). For example:

mymultisite.com/blog1
mymultisite.com/blog2

However, whenever navigating to the URL of those sites, the URL updates to a blog post URL. So instead of...

mymultisite.com/blog1

I get...

mymultisite.com/blog1/blog-post/

Besides the fact that it goes to the first blog post, rather than the most recent one, my main concern is that I cannot see the 'timeline' as one would on a singular Wordpress site. In other words, I can only see a single page for the entry. I figure this is probably "expected behavior", and may have to do with avoiding conflicts. But... how can I make it so that when navigating to the blog1 directory I get to see the whole timeline in descending order, rather than just a single post?
