I think consuming and producing information should ideally go together. Usually, I first talk about something I read with friends. Through these dialogues, where together you talk about what you have read, you gain new insights.
Some years ago I started taking private notes and shortly writing thoughts about events and articles I had read, which can be accompanied by sharing more elaborate thoughts on social networks. If I made a short note for something I read, I already started to read more carefully, because I knew I would have to write about it. It might have also made me more critical about the value of certain sources of information.
I'm now in the process of writing my first blogs publicly, on specific topics that interest me, but where I also know that at least certain friends / groups of people are interested in reading it. For me these are the first steps to make sure that I spend time on sharing thoughts and ideas that have value for others.
