One thing humanities scholars are really great at doing is reading, connecting ideas and writing about it. We know stuff! However, that work (and it is intellectual labor) is invisible and largely undervalued. Yet it forms the foundation of all good scholarship. All people see is the footnote on an article or a note in a chapter in a book. Humanities faculty, unlike their STEM counterparts, do not have labs. We do not have a place for our work and no one sees our process. While there are bibliographic managers that help scholars manage their sources, actually writing about the things you read and how they speak to each other in a way that people can access makes it more likely that humanities scholars will have conversations with others who share your research interests.
Sharing research encourages communication and the development of ideas and theories which is what research is all about so blog spaces and web spaces are a great way to achieve this successfully and across the web.
