I know experienced developers that have few or none activity in GitHub at all. So, it depends. You could find developers that: 1. write good code and are active in the community 2. write good code and are not active in the community 3. write ok code and are active in the community 4. write ok code and are not active in the community 5., 6., etc., (... you get the idea) So, with number 2, you could see an empty GitHub profile and perceive it as low quality, but that's the wrong perception. See `pyrophane` comment as example. Obviously on a hiring process a GitHub profile with activity is a great plus, but, again, it depends.
