The beauty of Micro.blog, is that it focuses all attention on what is being written.
From a post author’s perspective you have a box you can type in without a lot of formating controls that just distract you. And if you write too much it just effortlessly lets you continue in long-form.
From a reader’s perspective: blog templates are simple, uncluttered with everything focused on the content before you. This is by design not accident and it is brilliant not to distract the reader from what you are saying.
Micro blogging is, however, slightly different than a blogging completely in long form. If you only post long form articles then things like tags, categories and site search become more important.
