The core of my argument is: try to select as much as possible on what you care about (ability and desire to contribute and learn from lesswrong 2.0) and as little as possible on stuff that’s not so important (e.g. do they get references to hpmor). And do testing to work out how best to achieve this.
By intellectual community I wasn’t meaning ‘high status subculture’, I was trying to get across the idea of a community that selects on people’s ability to make intellectual contributions, rather than fit in to a culture. Science is somewhat like this, although as you say there is a culture of academic science which makes it more subculture-like. stackoverflow might be a better example.
I’m not hoping that lesswrong 2.0 will accumulate money and prestige, I’m hoping that it will make intellectual progress needed for solving the world’s most important problems. But I think this aim would be better served if it attracted a wide range of people who are both capable and aligned with its aims.
What about asking your audience questions?
For example, you could ask questions:
* Seeking criticism, such as “I think section x is the weakest part, what are some alternative arguments?”
* Promoting understanding, such as “Can you think of 2 more examples of <concept I just introduced>?”
* Stimulating research, such as “I think this model can be applied to area y, does anyone have suggestions for how to do this?”
This might help get readers out of passive consumption mode, and into thinking about something they could comment about. It would also make the writing more useful.
