Ev Williams just published his reflections on Medium’s mission five years in, 'Words still matter'.
I've been aware of the information I consume for about 5 years now. I have a vivid memory of discovering Quora in early 2013 and thinking 'wow, I've been consuming a lot of crap, I should try to read better quality articles'. I try to encourage my friends and my family to be aware too. But all of this is invisible. You don't see your brain. It's harder to notice. Also, you have fewer incentives to cultivate your mind VS to cultivate your body. People can't see it. But it's so important.
There's so much work to be done in that space. It's the next big thing after health in my opinion. Personally, I've been experimenting a lot. My current 'brain diet' includes Medium, Quora, a curated Twitter feed, Reddit, a few high-quality newsletters in very specific domains, some Headspace. A bit of Facebook/Instagram. No TV, no news. And damn it's hard. I feel like someone trying to avoid salt and sugar. It's everywhere.
Start taking care of your brain. Because, as Ev Williams is pointing it out clearly in his recent piece, nobody else has an incentive to do so.
