I've persuaded my very smart ex to start reading, but AFAICT reading the sequences after the fact is quite a lot more work than reading them was at the time, so unless I get around to scraping all the content and turning it into an eBook, it may be easier to wait until the book comes out.
If you want to convince averagely-rational people of something, be a living example of it working. Use that blog like the Internet native you are. Kill the Buddha and write your own understanding of it - you don't own the material until you could teach it, after all. You can expect people who know you to listen to you personally, because they know you. Give success stories - think of them as worked examples rather than anecdotes, if that helps.
Attract, don't push - EY didn't do a sales push for OB/LW.

I've been lurking on LW since shortly after it started, and on OB for about six months before that. In that time, I've told four or five people about it. I would make a terrible evangelist.
I'm curious as to whether other people have the same problem. I'd like to tell lots of people about LW, but I don't think they're ready for it. If they read a statement like "purchase utilons and warm fuzzies separately" their eyes would glaze over, and they'd walk away thinking LW was some sort of crackpot site.
I have found certain posts and topics to be fairly good hooks for getting people interested. An Alien God is a good suggested read for people with an interest in evolutionary theory and the Cthulhu mythos (surprisingly high crossover in my experience). HP:MoR is also a pretty popular hook. The site itself isn't really optimised for word-of-mouth, though, and not everyone likes child wizards and blasphemous horrors.
How many people have you introduced to LW? Who were they, how do you do it and what was their reaction? How could we do it better?
