Brian Tomasik is well-known in Effective Altruism for his prolific writing on reducing suffering, but in the last years he has been updating his website less and less. He recently wrote a post about the reasons for doing so (emphasis all mine):
Now that I already have a large body of online writings, the marginal value of additional writings is plausibly lower. If I were to write more, it would probably be about increasingly niche issues. But I think the main value of my writings is to get people interested via the big ideas, like wild-animal suffering, insect sentience, suffering-focused ethics, and the concept of s-risks. From that starting point, people can "graduate" to the more advanced research being done by organizations like the Center on Long-Term Risk and the Center for Reducing Suffering. […]
As the EA and suffering-reduction communities matured, they also had more money to spend on grants, as well as more people to connect with. I often felt that it was more useful to give some high-level thoughts on grantmaking and organization strategy than to write a new public-facing article for my website. […]
In the old days, many of my discussions about EA had been in public forums with other amateurs. This meant it was possible to consolidate insights from those discussions into public website articles. As EA became professionalized, more discussions became private, which made publishing insights from those discussions trickier. […]
These days, I tend to feel like you can only write "state of the art" and relatively error-free articles if (1) you're an expert in a particular field or (2) you're writing about something you know personally, such as an organization you work with or your personal life (which are special cases of being an expert in a particular field). People who for their jobs have to write about lots of different topics often get things wrong—sometimes small details but sometimes crucial points. […]
There's a saying that "young people think they know everything", and while that was never literally true for me by any means, I think a much weaker statement in that direction was true. When I was younger, I felt like I had important insights that needed to be expressed to a greater degree than I do now. These days, I've been exposed to enough intellectual viewpoints that any given one of them appears less special. Most new ideas feel like the same old kind of stuff I've been hearing for a long time. […]
I tend to become interested in more and more areas over time, as I get exposed to new things. This means the amount of time I have to spend on any given topic area is smaller, and it becomes infeasible to continue collecting information on each of those topics. I also realize that people can often just do a web search or consult Wikipedia to find a lot of relevant information, and I personally don't have to try to collect it. […]
Eventually I concluded that there were just too many new (and old) articles on the topic, and I didn't have time to keep adding links to them.
I'm reminded of what Brian Tomasik previously wrote in I prefer life in the slow lane - Too much literature to keep up with, which resonated with me as well:
One way out might be to do what Sarah Constantin describes in her essay How To Be An Educated Layman. I was curious about this, since her background is in math but she's written hundreds of extremely fact-dense essays on a wide variety of non-math topics, so she's as good an example as anyone. Quoting some parts:
Gwern also strikes me as someone who does this well; I think his "longtermist" approach to creating content is well-suited for pursuing as many super-specific questions as you want. Holden Karnofsky's learning by writing via minimal-trust investigations fits this mold too.
Thanks. :) Yeah, I think I sometimes can offer a different perspective than other people working on a problem (such as s-risks). A difficulty I have is that I worry that what I'm saying might be obvious or wrong, and therefore it's a waste of people's time to talk with me if I haven't read more of the background literature. But I still sometimes take the risk of wasting people's time just in case what I'm saying is actually useful.
