Members of "github is my resume" either don't work on critical projects that are under time pressure or don't have jobs that require them to code a lot. I was much more open to hobby coding when the job had unreasonable amount of meetings (or other socialization). When I was focusing on code/design most of daytime, I found out I was too tired even before 8 hours ticked.

Coding meant I will be less productive next day and besides, I was already coding a lot and getting better at it in work. I found it more rational to focus in my free time on things that job wont teach me.
