Top 5 things I like about SharePoint

Besides being a corporate news channel and storage for documents, can you name 5 things SharePoint is used for in your organization?

Let me help you with top 5 things I like about SharePoint:
1. Document management: documents and pages based on document/page templates and content types, and metadata driven navigation and search
2. User Profiles: clearly defined and easy to find user skills, responsibilities, and activities
3. Lists: more effective and flexible work with information held and displayed as calendars, surveys, car rental, tasks, Q&A etc.
4. Role based content: metadata (skills, department etc.) in your user profile defines the content that you see; news, documents, pages, and lists
5. Web 2.0: Even the corporate news can be a two way communication with comments and rating that allows you to contribute with your knowledge and opinion
