The pace of engagement is crucially important in a community of doers.
Moving too quickly and demanding too much, too soon, can leave volunteers frantic and feeling like they can't keep up. Moving too slowly can lose volunteers who do not see enough activity to hold their own interest.
The weekly IRC meeting has been a hallmark of most successful Fedora projects.

Either way, building and maintaining a sense of rhythm is crucial for a healthy community.
