The relation between a user and post count/views of a term can show the expertise of that user. However it is usually difficult and database intensive to retrieve those relations.
This module give you an API and many pre-built blocks to handle/display that information with easy. The performance is always optimized.
This module provides some blocks to show the expertise of an user. The expertise of a domain (a term) can be measured by:
- Total number of this user's nodes using that term
- Total views of this user's nodes using that term
- Total number of this user's comments in nodes using that term
There could be more things that I haven't figured out yet.
