Excited conversations between geeks tend to ramble a lot with a lot of interruptions, and while everyone's having fun, many conversational threads get abandoned as people get drawn into the new topic and forget what they were planning to say. I invented conversation queues for me and my friends. Whenever someone is inspired to tangent onto a new topic, they interrupt only long enough to point at me and say a word or two, which I write down. The next time there's a lull in conversation, I announce the next topic in the queue and cross it off, and the person who inserted it gets to expound. It seems to work really well, and the list can get quite long with a few hours over coffee or beer.
