What features will such a platform have? What modules provide these features? And what work is needed to wrangle these modules together?

Social networking

• Who's your friend? Who's just watching you?
  • modules: Buddylist, Relationships
    • User relationships looks great, but seems very incomplete (at least in Drupal 5.x)
• What are they doing
  • modules: Activity for onsite, Activity Streams for offsite

Discovery

• Who is like you?
  • modules: Neighbors
  • Self-tagging a profile as "Interests"
• What content is like this content?
  • modules: Similar, Related Content
• What content would you like?
• What groups would be of interest

Groups

• Allow users to create arbitrary groups, like Yahoo Groups
• Email integration (mail to group, receive mail from groups)
  • Mailhandler module?
• Group discovery -- How to find a group that you'd like
  • Broad classification for a top level (mozdex categories?)
  • Tagging of groups
  • Show groups that most of your friends belong to
  • Show groups that match your interests (see: user tags under Discovery, above)
• modules: Organic Groups, OG forums

Sandbox a user's content

• Make monthly archives, tags, related content, etc for a single user AND for the group
• Learn something from og.module on this?

Personal Profiles

• More than an about me, pictures, and comments
• Persons interests and relativism to the community surrounding the profile
• Default profiles should be easily tailorable to the community that is implementing the platform
