"When we read, another person thinks for us: we merely repeat his mental process. In learning to write, the pupil goes over with his pen what the teacher has outlined in pencil: so in reading; the greater part of the work of thought is already done for us. This is why it relieves us to take up a book after being occupied with our own thoughts. And in reading, the mind is, in fact, only the playground of another’s thoughts. So it comes about that if anyone spends almost the whole day in reading, and by way of relaxation devotes the intervals to some thoughtless pastime, he gradually loses the capacity for thinking; just as the man who always rides, at last forgets how to walk. This is the case with many learned persons: they have read themselves stupid."
It is funny how people who read a lot say the same thing about people who watch a lot of movies/series or play a lot of [video] games.
I suppose Usenet was the first public massively available cesspit to read and write. You could regard it as a practice ground for either.
With regards to creating content, it requires life experience in general as inspiration. You could obtain such life experience by doing things such as climbing or hiking or traveling or reading or watching TV or playing video games or interacting with random people on the Internet or going out every Friday night to the pub. Who's to say which of these are effective, or not? Why even make such a bifurcation in the first place?
For creating content in a particular media, if your life experience is mostly built from that particular media, all you would product will be derivative of that particular media.
