Company wide IRC type chat with several non-business chat channels to socialise in (eg. Tech, Food, Fun, Sport). Can use an IRC server, jabber/XMPP or Hipchat for this. Plus regular real world trips to meet/connect with the people you work with, and an active social life outside work. It of course helps if you're the kind of person that likes solitude.
