How Many Posts Per Page?

I just changed my blog's settings so it will display ten days' worth of posts on the main page, instead of five. Only days I post on are counted, which is why right now there are posts from as far back as June and not just from the last ten calendar days.

Do you have any preferences? Is it taking any longer to load now (though I don't see why it should, since I rarely add videos and pictures to my posts)? I'm open to feedback from all my avid readers. Yes, both of you.

Update (August 28, 2009): I've switched back to five days' worth of posts. I've shortened the list of labels, so a shorter first page is more suitable, in my opinion.
