Blogs aren't showing up

Okay, I've got a network set-up (with Buddypress installed, as well) and my users can create a blog.

As admin, I just created a blog... it should be at

However, when I go there directly I just get a blank page.

If I create a post for it and click to view it, it takes me to a page that looks like my Buddypress activity and I see the post there.

But, why am I getting a blank page going to it directly?
