I have multiple github profiles, because GitHub did not allow me to keep commits to certain public repositories from being broadcast to my public activity feed on my profile. I did not want to broadcast certain commits to the world just yet, so I made a new account for that purpose. Now that I can set my whole profile to private, I can try to merge the accounts.
