Blogger kept nagging me to update to their Beta version, so I finally did. So far, the only new feature I've used is the labels you'll see at the end of each post.
If you click on a specific label, you'll be taken to a page containing all the posts that also have that label. So, for instance, if you want to read all my homilies, click on the preaching label at the end of the most recent one, and you'll get all of them (along with a few preaching-related posts that aren't actual homilies).
This is a useful sorting system, and should make it easier for readers to find material that interests them.
