There's the stream and there are blog posts. Somewhere in the middle are noteblogs. The best example of this I've seen so far is Quartz's new noteblog about TV, Glass. It has the lightness of a Twitter stream but the in-post detail of a blog post.
I've started a new noteblog at called Pieces where I want to collate links and ideas I find interesting on the net. This will remain a more personal noteblog.
