Sure, and I was that person with the svn -> git migration at a different gig. Ideally our behavior matures over time.

For me, at least, two things eventually made git really manageable: github and the O'Reilly book. After those git was a no brainer. Even with git becoming the de facto standard, if you don't need the integrations it's not so unreasonable to use something else (altho bzr's been discontinued).
