Hi David, your social media profiles are pulled in automatically from Gravatar, just like your photo.

We tried to make sure all WordCamp speakers were imported, but not all WordCamp organizers have entered that data, especially for older camps. Please post a comment on http://make.wordpress.org/community/2014/02/23/past-wordcamp-organizers-help/ with your username and the camp you spoke at and we'll get it fixed :)

Not all plugin/theme authors have been imported yet, but we're working on that too.
