Proposal: 7 Core Use Cases For The Social RWW?

I've been looking at the mechanics of facebook and they seem to have 7
chief interactions (represented by dialogs)

I propose that we try and include these into our social read write web
systems:



User Interactions
==============

1. Adding a friend

https://developers.facebook.com/docs/reference/dialogs/friends/

2. Sending a message to a friend

https://developers.facebook.com/docs/reference/dialogs/send/

3. Sending a request to a friend

https://developers.facebook.com/docs/reference/dialogs/requests/



Feed Interactions
================

4. Adding a post to a news feed

https://developers.facebook.com/docs/reference/dialogs/feed/



App Interactions
============

5. Adding an app

https://developers.facebook.com/docs/reference/dialogs/add_to_page/

6. Setting app permissions

https://developers.facebook.com/docs/reference/dialogs/oauth/



Payment Interactions
================

7. Adding a payment

https://developers.facebook.com/docs/reference/dialogs/pay/



I think we're almost at proof of concept stage with most of this.  But
perhaps if we can get decent demos working for each of these use cases, it
can be a good showcase of what the read write social web can do?
