I like that it is easy for people in different areas/departments within an organization or across organizations, etc.,to find each other with ease when they need help from someone working at another location (e-mailing).
The search function could be more robust--perhaps better integration into EWS would make this possible? We are trying out carbonclick as part our larger initiative around corporate social responsibility and sustainability reporting which includes multiple data sources such as CO2scope but also include some external resources e.g.: UNEP's Sustainability Reporting Framework; CSRHub reports - we're looking forward using these together!
