Yes, for Steve Sjogren and the rest of Vineyard Community Church in Cincinnati, the church has left the building -- gone "outreaching". Steve is the pioneer of the Servant Evangelism movement. The movement implies that Christians can't be truly effective in Mission if they become introverted spiritually. Followers of Jesus need to reach out and help others, to share God's love. The Servant Evangelism site contains many great ideas for outreach. They also have a FAQ-type page.
So ... is your church reaching inward or outward -- involved in outreach or "inreach"? I have a suspicion that when churches collapse inward spiritually, they become like a black hole, which doesn't even let light escape. Except in those churches, it's the Light of Christ that isn't escaping.
