You can now add your Twitter username to your GitHub profile directly from your profile page, via profile settings, and also the REST API. We've also added the latest changes:
- Organization admins can now add Twitter usernames to their profile via organization profile settings and the REST API.
- All users are now able to see Twitter usernames on user and organization profiles, as well as via the REST and GraphQL APIs.
- When sponsorable maintainers and organizations add Twitter usernames to their profiles, we'll encourage new sponsors to include that Twitter username when they share their sponsorships on Twitter.
