Hi Chris,

I checked the developer's guide for opensocial on code.google.com. Now when 
posting articles, it refers to the activity stream which defines the action 
performed by any user. Now why are there two tables for this used in pertuza. 
One is the activity stream table which stores the actions of a user and the 
other is activities table which again stores the activities. Difference is, 
activity stream only stores the person id and the title, where as the 
activities table stores the person id, app id (why is this required?), the 
activity title, its description and time of creation. The activities can be 
fetched from the activities table, then why is the activity stream table 
required?
