Am I the only one who thinks some more competition would be nice? I would like to see more code move into BitBucket or similar. New version of Kiln will make it possible to use Git and Mercurial against the same repository which sounds like a great feature (not sure if there is a free plan on Kiln yet).
Sorta. The eggs you're placing into github's basket are different from the eggs you've decentralized. I'd argue those eggs (merge requests, issue tracking, discussions) have never really been successfully decentralized.
