An early adopter is someone who is first in line to try something new, usually because they're willing to build part of the new thing with their own hands. Just look at what projects are on any of the third-party forges, those are the early adopters of post-github tech.

I would also be one of them, but I'm not actually off Github yet. That's because I haven't quiite finished building the thing I'm going to move to.
