I love the look of the new profile page, and it's great that it's got a field for your GitHub account, but what about us poor Bitbucket users? I know I can't expect Stack Exchange to support every source control host under the sun, but including Bitbucket would be great.
Edit: I abandoned Bitbucket after they dropped support for Mercurial. Not much point in using it anymore, it's just a GitHub clone now.
