Agreed. I realize that the words like "litany" and "conspiracy" are used semi-ironically, but a newcomer to the site might not.
This wording may lose a few people, but it probably helps for many people as well. The core subject matter of rationality could very easily be dull or dry or "academic". The tounge-in-cheek and occasionally outright goofy humor makes the sequences a lot more fun to read.
The tone may have costs, but not being funny has costs too. If you think back to college, more professors have students tune out by being boring than by being esoteric.
I have several questions related to this:
If you visit any Less Wrong page for the first time in a cookies-free browsing mode, you'll see this message for new users:
Here are the worst violators I see on that about page:
And on the sequences page:
This seems obviously false to me.
These may not seem like cultish statements to you, but keep in mind that you are one of the ones who decided to stick around. The typical mind fallacy may be at work. Clearly there is some population that thinks Less Wrong seems cultish, as evidenced by Google's autocomplete, and these look like good candidates for things that makes them think this.
We can fix this stuff easily, since they're both wiki pages, but I thought they were examples worth discussing.
In general, I think we could stand more community effort being put into improving our about page, which you can do now here. It's not that visible to veteran users, but it is very visible to newcomers. Note that it looks as though you'll have to click the little "Force reload from wiki" button on the about page itself for your changes to be published.
