Arbital's initial goal was to create a centralized place for math explanations\. This allowed us to build the foundations for a wiki platform as well as learn how to think and act as a startup team\. We got experience nurturing and working with a small community, listening to feedback, and quickly iterating on the product\. Current software is flexible enough to support blog posts, claims, discussion, and other entities we might want the platform to have\.
Links to examples would go great here.
