There should be an option to create multiple blogs with the same account. Sometimes people have interest in multiple, completely unrelated areas. Posting them all under the same name would make it more difficult for readers to find the posts that they are interested in.
Also, there should be a way to save "must read" articles much like favorites or playlists on YouTube. This makes it easier for users to find articles that they have read and liked, allowing them to easily pull it up and share it whenever a situation arises. Users and content creators can also use this to share related content to their followers easily.
