In Dolphin there is an option to subscribe to a blog post, but not to an entire blog. It seems a little odd, as a blog post is not something which is commonly changed (and most users don't really care if it does), but it is quite reasonable to want to subscribe to the entire blog of an interesting person, so you get notified when they post a new blog entry.
I'm afraid many of my users are going to think they do just that, when in fact they only subscribe to a single post.
Do I miss any reason behind it?
