We would like to extend the functionality of Sharepoint 2010 to improve the Social Networking Features.

We want to trace a sharepoint 2010 user events, whatever he/she performs on the site collection level.

Say:
Uploading a document into the document library
Adding an item into the list
Adding a discussion or Repling for a discussion
Uploading an image into the Image library
Involved in any of the workflow activity
changing his social status
Posting a Wiki /Blog
Any changes in the caldenar List
Any changes in the Task List
Setting/Modifing Alerts
Any updates on the Announcement list
Contacts update
Colleagues added/removed

How to achieve this?
