In vancouver, we've been doing discussions of How to Win Friends and Influence People. One chapter a week. About half of us come in having read the stuff, but overall we get good discussions, and the people who havn't read stuff are able to pick up on the material and participate.

Also did Map and Territory sequence last time. Worked well. Doing Mysterious Answers tomorrow, it's a bit longer, we'll see how it goes.

It seems like you only really need one person to have really read and understood everything, as long as other people have seen enough to actually discuss the topic and pick up on the gaps.

It really helps for someone to summarize the main points of the article/sequence before the discussion. Like just write down a list of major points and give a short blurb on them, then discussion organically continues from there.
