As I categorise my posts of things which interest me the associated word cloud comes to uniquely identify me. The current visualisation is only one of many which can be produced. As a teacher I am showing students to extent of my interests in a way demonstrating (hopefully) research-based teaching.

If a group such as a university department/ faculty were all to categorise their research and teaching and learning interests in this or other compatible way then it would be possible to create group profiles.
