- Each blog has an RSS feed (all flavors) but not Atom. It’s not clear which services a blog pings with updates.
- A “favorites” system, lets you add a blog to “My Favorites” and see their updates in a sidebar of your own blog. The number of fans you have (favorites subscribers) shows in your stats. This is a great way to use RSS feeds within an application.
- Like Ryze and other social networks, you can leave a message in a Guest Book, essentially commenting on the blog instead of a specific post.
- Access control over posts, like LiveJournal. So you can have a post that’s private to the author, to named friends, or to a named group.
