I would like to explore your belief, Louie, that increasing the rate of growth of LW is desirable.

ADDED. Clarification: interventions to increase the rate at which new people join LW are good IMHO when the current rate is low enough not to overwhelm the "mechanisms for newbie assimilation". So I guess I want to ask Louie if he is measuring the rate of new arrivals and whether he plans to discontinue the adwords if that rate gets too high.

ADDED. Last time there was a meetup at Benton house, I told Kevin that I wish he had waited with his efforts to apply "search-engine optimization" techniques (to increase participation on LW) till LW had more time to assimilate the influx from Methods of Rationality. I hope I am not misrepresenting Kevin, but I got the distinct impression from his reply in that short conversation that he recognized no good reason for LW not to grow as fast as possible. (Of course, Louie is not Kevin.)

I certainly do not object to the goal of building more rationalists (as you put it) but I worry that too fast a rate of growth might drastically decrease the usefulness of LW as a place to learn. And I worry that it would cost a lot more to reverse that decline that it would to prevent it.

Do you perceive that LW's usefulness as a place to teach and to learn has decreased since its founding?

Do you believe that as LW grows it will become a less useful resource for learning for people who are already very strong rationalists? I would not mind if that proves to be the case BTW if the growth helps larger numbers of less-strong rationalists: I just want to know what the objectives are of those making significant efforts to improve LW.

I do not think that anyone will dispute that most online conversations (forums, group blogs, boards, etc) lose their usefulness after a few years in a way that is difficult enough to reverse that one might as well just start over with new software, new rules or new owners. Paul Graham maintains that the conversation he runs (Hacker News) is constantly on the verge of failing and that only constant interventions by Graham and his helpers prevents that from happening. In particular, Graham considers growing too fast to be a potent risk to Hacker News.

To what do you attribute the uncommonly high usefulness of the LW up to now relative to other place to learn online?

Which practices (deliberate or accidental) do you believe have maintained or will maintain the usefulness of LW as a place to learn and to teach?

What signs (if any) would cause you to come to believe that LW's capacity to assimilate new voters and new contributors has been pushed to its limits and that attempts to grow LW should be suspended until the capacity has recovered?

What fraction of LW comment do you personally "vote on" (make a decision as to whether to upvote, downvote or leave alone)? ADDED. Reason I ask this is that voting on many comments was much harder work than I thought it would be before I tried it. (The hard work came from the need to avoid or recover from an overly judgmental and critical mood that would have had a deleterious effect on my non-LW life.) Consequently, unless my experience with voting was atypical, anyone contemplating an action that would add significantly to the work done by LW's voters should probably have significant experience on voting on a signficant fraction of LW's comments unless he or she has some other way to avoid overextending that particular resource.

ADDED. The tone of this comment is probably too strident. It is important to keep in mind that since it is relatively inexpensive to start a new group blog, forum or other "place to teach and learn" on the internet, the "loss" of LW is not all that expensive. Nevertheless, I am curious as to why I seem to be deep in the minority in certain perceptions:

The way LW has been since its founding is that anyone who registers can start voting, and I am aware of no plan or proposal to change that.

Perception One that I have that does not seem to be shared: it is easy to design a system better than what I just described. E.g., require new registrants to accumulate 20 karma before they can vote.

Perception Two: there are some simple numbers that could be collected by software in a straightforward way that are not being collected such that if one of the numbers took a sufficiently steep downturn, that would be a strong sign that any efforts (like sending readers of Methods of Rationality here, asking people to promote LW on StumbleUpon or buying adwords for LW) to increase the rate of growth of LW should be curtailed for the time being. One of those numbers is the rate of voting by accounts older than 2 years (those accounts being more likely to be able to vote in such a way as to keep up the standards of LW) as a fraction of total votes (or as a fraction of the votes made by those accounts during the same time frame last year). Another of those numbers is the number of comments made or number of words posted by accounts older than 2 years. In other words, it seems like a basic precaution to me to make sure that the new voters and the new writers on LW are not driving away the old ones.

Again, I am not opposed to trading off average comment quality for increased educational reach if that is the direction those who do the work to maintain LW want to take, but there's a difference between consciously making that trade-off and losing LW while neglecting to use the loss to collect any data useful for improving the robustness of future online conversations.

Perception Three: Since a person who has figured out how to use one web site will have very little trouble figuring out how to use another one, the higher the quality of a conversation on the web which anyone can join, the more difficult it will be to prevent that quality from regressing to the mean quality of conversations on the web that anyone can join -- and a conversation has to be far above the mean quality for it to start to compete with a competently-chosen college or textbooks as a way for young aspiring rationalists to learn.

Perception Four: Even though LW is vastly better as a place to teach and to learn and for people to cooperation on projects to improve the world than the average place on the internet, it is possible to imagine places on the internet that are much better than LW. Effort put into understanding how to preserve or maintain the quality of the conversation on LW can probably be applied to making it even better. I.e., the optimistic outcome of work on "online conversation quality" has very high utility. I.e., this is not just about avoiding the need to find another place to teach and to learn because LW has become useless for that purpose.

Specifically, there are probably tricks we can learn to improve online group rationality without needing to improve the rationality of the group's members. By "improving group rationality" I am imagining mostly (1) making teaching and learning online less irritating, less addictive and more time-efficient and (2) making world-improving projects more effective without increasing the individual effectiveness or rationality of the teachers, learners or project members. What people like Paul Graham, Clay Shirky and Teresa Nielsen Hayden know about maintaining online conversations is quite relevant here IMHO.

You could browse the LW favorites post and best of series for ideas.

Generic method is to search google for "site:lesswrong" to see what already has high page rank and is therefore considered useful by people linking to the site from outside. I found that a lot of tags come up that way so I tried this search: "site:lesswrong.com -tagged".

Going down a page or two and then looking around I found these that might be cool:

1. Lotteries: A Waste of Hope

2. Science Isn't Strict Enough

3. Absolute denial for atheists

4. Good Idealistic Books are Rare

I don't know what keywords to use, but 37 Ways Words Can Be Wrong is a good one.

I just realised something: could SIAI/FHI demand you take down those ads, if they didn't like them? If not, what's to stop malicious people from advertising another's website in a way that makes it look bad, or that has unwanted consequences (say, "4Chan - for all your sparkly vampire needs")?

People who go specifically looking for information on how to think ought to be directed here, so perhaps some keywords related to thought in general: "thinking", "confusion". And some likely terms people would make up for thinking-about-thinking: "metathinking", "metathought", "wrongness".

Surprisingly, there's not much advertising if you search for "politics". I feel like that ought to redirect to Politics is the Mind Killer.

All of the advertisements, and the top result for "philosophy" are, strangely, about cosmetics. I don't know what's up with that, but people searching for that would be better off here.

In dicussion of free will, I've blown quite a few minds by linking them to Thou Art Physics.

The primary causal reason I'm here is because Eliezer's prose is entertaining and engaging. I'd link to the most entertaining posts, the ones that are fun to read, like Disputing Definitions or maybe Stranger than History. I'd also avoid posts that look like they're advocating a particular viewpoint, since humans tend strongly to dismiss such things as "oh, he's trying to persuade me of something".

I really like That Alien Message and it has done well (more than once) on Hacker News and reddit.

http://lesswrong.com/lw/qk/that_alien_message/

Not sure what keywords to bid for -- probably science fiction related keywords.

For many terms that are relevant (Bayesanism, rationality), LW is already on the top set of Google hits. So I don't know how much return this sort of thing would get.

Try to get people who google 'meaning of life'?
