Roam Research (aka Roam) is a silo that functions as a personal wiki, to do list, digital notebook, or commonplace book. It can either be public or private and thus could be used as the basis for a website, though there isn't a way to map a personal domain name onto the service.
Among many common website features, Roam has the ability to:
- tag or categorize content
- provide backlinks or bi-directional links between pieces of content
- provides a mind map view of links between pieces of content
