Two people, preferably friends, collaborate on a blog post by being available to one another. One begins by sharing something interesting, then commenting on it. This begins a dialogue. The second person then reciprocates with something they like which follows the thought-path of the previous item. The two go back-and-forth ten times and see where the flow of the conversation takes them.
Topics and titles aren’t discussed before-hand. The process is more an unearthing than a construction. Like a good conversation, it is an improvisational process that relies on the acceptance of the ideas of the other individual.
