Nothing more specific than that? Was it too long? Too many big words? Too conceptually difficult? Too much citing of scientific studies? Too many basilisk scandals?
Lol on the basilisk scandals, I wish they had enough interest to explore that topic.
Most of the feedback from those editors cutting the links was that it was "inappropriate." It's a short-hand for anything they don't think will resonate with their readers. When I asked why, they generally don't respond and I have to go with that if I want it published. Some say it's too difficult for their readers, in terms of long words and concepts. Some say the content and design of the website is offputting - and it's not a surprise, given that self-improvement websites often focus heavily on graphics, and LW is almost exclusively text-based.
Nice to get this list-style article promoting LessWrong, Rationality Dojo, and Rationality: From AI to Zombies, as part of a series of strategies for growing mentally stronger, published on Lifehack, a very popular self-improvement website. It's part of my broader project of promoting rationality and effective altruism to a broad audience, Intentional Insights.
EDIT: To be clear, based on my exchange with gjm below, the article does not promote these heavily and links more to Intentional Insights. I was excited to be able to get links to LessWrong, Rationality Dojo, and Rationality: From AI to Zombies included in the Lifehack article, as previously editors had cut out such links. I pushed back against them this time, and made a case for including them as a way of growing mentally stronger, and thus was able to get them in.
