Everyone is for,  likely doesn't mean the same thing for everyone. Let's try to share a common list of ideas we ought to add to CiviCRM.

Social Network integration with CiviCRM has different facets

• track social media identity for contacts
  • would be great if this could work like the Rapportive app in Google Apps, where accounts for a contact are actively searched/guessed at for a variety of social media properties (maybe we could integrate directly with Rapportive)
• being able to fetch information about contacts from social network sites. Eg. being able to update a contact's email if it changes on her facebook record, such as Emotive's work on Facebook integration
  • allow display of profile info for a contact gathered from these sites, eg employer, job title from LinkedIn, interests from Facebook: useful when about to call a contact, or deciding how to segment them
• being able to gather activity info from social networks and feed it to CiviCRM (eg. save #relevant tweets in civicrm)
  • would be good to create activity records in CiviCRM for all existing (and new??) contacts who use a particular #hashtag or combination of #hashtags, either for the organization, or for a campaign
  • may create db bloat: should we just try to integrate our search with external results, allowing CiviCRM searches to include, e.g. those who sent a particular Twitter hashtags in the previous month
• being able to let visitors use their social media accounts on CiviCRM pages:
  • promote a CiviCRM entity on the social networks (like, tweet, G+) an event, a donation, a petition from a CiviCRM page: requires logins for contacts' accounts to those other networks
  • being able to use a social network like another media, eg being able to @ tweet a user or set of users, perhaps as an action on search results
• being able to expose CiviCRM in social networks, eg. being able to sign a petition from Facebook or register for a CiviCRM event from MeetUp
  • might involve, e.g., choosing to expose a CiviCRM page using a different output filter for Facebook markup.
