I've chosen to print articles for ~10 years, as it was the easiest for me to read during commute. Content is also much easier to make sense of on paper, as we can scribble notes anywhere. I wish e-readers evolved faster to allow for a similar experience.
Although I've now stopped printing stuff; I care a bit more about the planet than I did back then.
Now I long for solutions to help me curate and organize content.
