I realize I haven't given a direct answer yet, so here it is: I'm in, if I'm wanted, and if some of the changes discussed here take place. (What it would take to get me onboard is, at the least, an explicit editorial policy and people in charge of enforcing it.)

There was a sudden exodus of talent, which reduced posting frequency, and took the wind out of the sails.

I'd be wary of post hoc ergo propter hoc in this context. You might also have expected that by leaving for other projects these posters would create a vacuum for others to fill. It could be worth looking at why that didn't happen.

Yes, and this would be a general trend - affecting all community blogs to some extent. I was looking for an explanation for the downfall of LessWrong specifically, but I suppose it's also interesting to consider general trends.

Would you say that LessWrong is particularly prone to this effect, and if so because of what properties?

This feels like a good start but one that needs significant improvement too.

For instance, I'm wondering how much of the situation Anna laments is a result of LW lacking an explicit editorial policy. I for one never quite felt sure what was or wasn't relevant for LW - what had a shot at being promoted - and the few posts I wrote here had a tentative aspect to them because of this. I can't yet articulate why I stopped posting, but it may have had something to do with my writing a bunch of substantive posts that were never promoted to Main.

If you look at the home page only (recent articles in Main) you could draw the inference that the main topics on LessWrong are MIRI, CFAR, FHI, "the LessWrong community", with a side dish of AI safety and startup founder psychology. This doesn't feel aligned with "refining the art of human rationality", it makes LessWrong feel like more of a corporate blog.

Form and content are not that easily separated. For instance, I like #15 (a bit), because the typography fits the message.

Instead, I'd suggest you focus on design that reinforces, ideally in a humorous way, the message of the slogan.

I feel strongly that "Please Provide an Example" ought to have the word "example" consist of hairy green ball things, in homage to Fenyman's famous explanation of how he would debug math or physics claim by turning abstract concepts into imagined examples.

"I notice I am confused" could play on a classic "magnifier" icon in the word "notice", and jumble up the letters of "cnfosued", or mess up their typography.

To put this in some perspective, they're mostly doing it because the Brits did it first.

Still, having any recognition and awareness that there is a problem there is heartening. We're just getting started here; last I heard, the good old habits were still in force, i.e. of starting software efforts with price tags expressed in hundred million euro multiples, letting them run for a while, then scrapping them as not even worth deploying.

Procurement is one of the big culprits here; a classic case of lost purposes. Ostensibly to save money, departments give a lot of power to policy-making bodies who then dictate a risk-averse process that departments must follow before they can spend their own money. This means that contracts now mainly go to contracting firms who positively relish dealing with red tape, but are less competent at actually shipping code.

Typically this leads to disasters, see above, which result in tightening financial controls, giving even more power to purchasing organizations, the almighty tail wagging all the dogs. The departments' own IT people, in this setup, end up doing nothing much beyond filling out paperwork, while all actual competencies such as writing the software are "externalized" to contractors.

So the job description is basically to cure government of this addiction. I've been given control over a budget of a couple million euros to start with, and instructions to split it over about 10 worthwhile projects this year. Each project should have a 6-month roadmap, with a first go/no-go milestone at two weeks in (and an obligation to report in with something they've learned by getting out of the building and talking to end users). At least half of the development crew (4 to 6 people) should be in-house to the departments, not contractors. That should leave much less room to hide incompetence, but we'll also provide a bit of mentoring to make sure these teams know a minimum of good engineering practice.

  • A couple months ago I started learning the Elm programming language, and to make things interesting I resolved to push one non-empty code commit to GitHub every single day (ideally also non-trivial, but not everyone's definition of "trivial" will match mine). I'm now on day 67 of that streak, having written six proto-games (playable here if you're so inclined, though they're not hugely entertaining). So far the habit has resisted a new job and a ten-day vacation. I've also been keeping a daily journal since Feb 21.

  • Used my 3D printer (Prusa i3) to print the entire set of plastic printed parts for a different printer (FoldaRap), very much a non-trivial project (~ 50h of printing for 30+ distinct parts) that requires a well-tuned printer. I'm particularly proud as this comes on the tails of completing a major conversion of the Prusa from its original direct-extrusion design to a Bowden setup.

  • Got hired by the French government to promote a more agile style of programming and project management.

This continues to be a puzzling topic...

My most recent explicit thought about this had to to with teamwork: it's become a commonplace that "conflict in a team isn't actually bad", and I was thinking that conflict per se may not be counterproductive, but I would certainly view engaging in dominance contests as a waste of time all around.

When I coach teams I often consciously adopt (and advocate for others in a similar position) a "low posture" - a cluster of heuristics, really, such as "I'm happy to help the group work through a problem but I'm not the one who makes the decision", or "invest significant time in hearing people out".

There can also be a question of perspective: some people are determined to view the world through dominance-tinted glasses, others to see it in tints of warm fuzzy.

Interestingly this article offers a QUALY-based economic estimate, but for some weird reasons plucks a wild ass guess as to the average number of years of life lost as a result of medical errors - ten years, with not the slightest justification. Of course this leads to a largish estimate of total impact.

This other article updates the estimates of annual deaths in the US to 400,000 with a lower bound of 210,000. This may be the result of misapplying an estimate of what fraction of adverse events are preventable - this was estimated on the overall sample (including non-fatal adverse events) but then applied to the much smaller set of fatal adverse events. Most fatal events result from surgery, which the same article notes has a much lower rate of "preventable" events, but I can't see that the total deaths estimate accounts for that.

Now that running regularly, for fitness and to keep my weight down, is a well established habit, I've signed up to run a half-marathon next March. (Not without a twinge of sadness, thinking of Hal Finney.)

Instead of just going out for a run on sundays and the occasional weekday, I'm now "following a training plan", that is, running workouts with specific targets, using a heart rate monitor, and so on. It makes some interesting differences and I've learned a few things.

One aspect of keeping fit that I'm still somewhat failing at, despite much self-monitoring and various attempts at behavior change, is getting more sleep. I'm still sleep-deprived (less than 5h) two or three nights a week.

Built a 3D printer from a kit. Learnt enough G-Code and OpenScad to be dangerous. Designed a few parts of my own, including some that replaced original parts.

Lost about 6 kilos from my max weight. Anecdotally, what seems to have worked in my case was eating lots more vegs, liberal amounts of meat, and about half my previous quantity of carbs. Also increased exercise a fair bit, incorporating a lot more walking (to or near the oft recommended 10K steps a day) in addition to a weekly run (typically 10K). One of my major objectives was to not feel like I'd gone on a diet, but instead to rewire my preferences so that eating whatever I enjoyed would lead to weight loss. I worked quite a bit on identifying and removing the trivial inconveniences that were keeping me from enjoying vegs and salad more often.

Switched banks. Sounds easy when you write it like this but it's an insane amount of hassle.

Let's discuss a new type of Reverse Turing Test.

This simply consists of coming up with a general class of question that you think would reliably distinguish between a chatbot and a human within about 5 minutes of conversation, and explaining which feature of "intelligence" this class of question probes.

If you're not able to formulate the broad requirements for such a class of question, you have no business being the judge in a Turing Test. You're only playing the chatbot as you would play a video game.

One of my candidates for questions of this kind: ask the interviewee to explain a common error of reasoning that people make, or can make. For instance: "If you look at the numbers, there's quite a correlation between sales of ice cream in coastal locations and number of drownings. Some people might be tempted to conclude that ice cream causes people to drown. Do you think that's right, and if not, why not?"

For another example, Dennett discusses having the chatbot explain a joke.

ETA: Scott Aaronson passes with flying colors. Chatbots are likely to lack basic encyclopedic knowledge about the world which every human possesses. (To some extent things like the Wolfram platform could overcome this for precise questions such as Scott's first - but that still leaves variants like "what's more dangerous, a tiger or an edible plant" that are vague enough that quantitative answers probably won't be accessible to a chatbot.)
