OK you can't do origami with it but platforms such as Blogger, LiveJournal, Wordpress, and even one of the originals, Diaryland, let you do so much. They can be a secret diary, just click private, or they can be a forum, self-publishing, an ePortfolio, a gallery for photos (or video), even a shared 'wiki-like' collaboration.
This isn't a blog, it is electronic paper.
