Hi again,
Ok, I understand now. You can kind of do this, but for the most part, you only have one timeline in the blog - multiple pages won't show multiple timelines.
So here's a few workarounds. The first one (which I'm not sure you're going to find suitable, so let's get it out of the way) is to set your home page as static, and then all posts will be on a page other than your home page, which you can designate (all posts, though, so no splitting the stream). You can read more about it here:

The next option may work better for you. You can display specific posts on category pages with our custom menus feature. This is more information about custom menus (see specifically the section about category pages):

If you decide to go with a custom menu and think you'll need some help setting it up, I'd be happy to help! Just let me know.
Cheers!
