The disconnect is, I believe, between the two distinct parts of Micro.blog - the hosting/blogging platform and the social community. The former wants to be open and supportive of every open protocol, which is an admirable goal. On the other hand, the latter is more insular and even a bit anti-social (or introvert-oriented), which makes it distinct from all other social networks, open or not.
If these were two different teams within the same company, I would love to be a fly on the wall during product meetings where each advocates their values and their value to the company. The fact that it’s all run and dictated by one person makes it more interesting but also confusing to communicate to the people using the product.
