Changes to Post Excerpts and Number of Posts on Main Blog Page
As requested by several writers, the standard length of post excerpts is now much higher. Post excerpts are shown to readers who have not yet subscribed, included in e-mail sent using E-mail Page, and placed in your syndicated headlines (in RSS format). You can see what the excerpts look like by signing out before viewing your blog.
You can now adjust the excerpt length as well as the number of posts shown on the main blog page. To do so, select "Change display settings" on your blog editing page.
