Different communities have different norms when it comes to writing and content production. One stylistic difference the EA community has, is that forum posts are often comparatively long, deep and advanced. I really like aspects of this and I think that having a relatively high level of depth can be very nice to offset the other mediums of communication EA uses (e.g., facebook). However, I wish EA forum authors would give content density a little bit more consideration.
Different books have different levels of content density. Some have a strong concept on almost every page (a good example of this would be Ray Dalio's Principles), while other books could be summarized fairly easily into a single, short blog post (I think Carol Dweck’s Mindset falls into this category). There is often a strong social pressure to make something ~book length, so even if it's a bit concept-light it will get stretched to meet a word count. In the world of blog posts, no such limit exists but there are social norms that tend to affect the average duration. I think for entertainment blog posts there can be a lot of value in longer-form writing (e.g., Wait But Why’s writing), but for blog posts that are aiming to get a concept across (like this one) a leaner form of writing would be better. I do agree we should try to make writing entertaining, just not with huge length increases as a trade off. (A good example of both high content density + low wordcount).
Why we should aim for higher content density
Time limited: Many EA forum readers are time limited and thus it is often a worthwhile trade to write a post that covers 90% of the value and is half as long. I often see blog posts that have a good concept or two, but due to how long they are they get far less engagement and readership than they would otherwise.
Counterfactuals: There is quite a volume of posts on the EA forum and this directly ties into most readers' opportunity cost. Oftentimes the trade-off might literally be reading two EA forum posts vs one that is double the length.
Approachability: EAs are a fairly technical bunch and although the use of jargon has been written about, having a high volume of content with relatively sparse concepts also makes it harder for new people to get up to speed. It can make the forum as a whole seem more intimidating than it has to be.
Length: The rule of thumb I use for blog posts is ~0.5-1 page per major concept and 1-3 pages per blog post. This kind of cap creates a strong force toward brevity and conveying concepts concisely. It does sometimes require major editing (the quote “I would have written you a shorter letter but did not have the time” comes to mind).
TL;DR and summaries: I think the EA forum makes great use of these and they are worth including in almost every post that is over one page.
Top concept leveraging: I think blog posts often try to cover a large number of topics that could easily be broken into multiple posts. For example, this data on value drift post being separate from this strategies for preventing value drift post makes each piece of writing much more individually referable and digestible.
Some examples of content-dense writing include:
Further reading: Steven Pinker has some really well-articulated and pointed suggestions for community writing norms, many of which I think would apply directly to the EA forum.
