@jwurzer The thing with micro.blog is that it has an inherent duality: it is primarily a (micro)blog hosting service but also incorporates a social element. That it displays (blog)posts in a timeline lends itself to being seen as a social network when this isn't, necessarily, its core function. Original posts being juxtaposed with replies (comments) adds to this perception.
When you also consider that you can use M.B as a hosted service (you pay to have your blog here) or self-hosted (you supply your existing RSS feed) this duality is increased as there is no core operating model. It is different things to different people.
It was never intended as a Twitter replacement per se but as a quasi-distributed network conforming to Indieweb principles that allows people to post,read and respond to blogs in a more social manner that encourages ownership of content.
