Why do we have to make everything so forcefully career driven? Just enjoy writing code and showing it to the world if you want - no strings attached. Github helps in this case.
Hence the topic.
Having a Github profile is "being forcefully career-driven" because it's now a potential gate put in place to work at increasingly more companies.
Because a lot of us have to code for a living, and employers often ask to see GitHub projects.
None of us are choosing this. It's just one of the many shitty trends in the world of software HR.
