I code for several reasons. It's what I was thought on college, it's what I do for a living, it's what got me the role I have now (quite an achievement) and is what I'm doing while I'm getting better at the other skills I need to do something far greater with my life that won't require coding anymore.
In a way, I agree with you that people should do more with their lives instead of spending most of sitting behind a computer. Then again, I think there are some people who wouldn't like that. Doing something different will require a change in mindset and other stuff that would be too much hassle for them and the comfort zone looks more appealing.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
