I grew up going to a lot of 'home churches', as they're very common in Evangelical/Pentecostal circles. And even in bigger evangelical churches there is still a strong focus on these 'micro gatherings'. these bigger churches often treat the Sundays as the 'evangelism' meetings (simple sermons, a lot of often high-quality entertainment, etc.), and then have the more in-depth bible study and interpersonal connecting in the weekday 'small groups'. These are usually in someone's house, and while they have a 'leader' the evening is usually taken care of by a different person in the group each time. It's in these house meetings that people often share more personal things and make their deeper friendships. It's a very nice and very successful model, and sometimes I wish the 'atheism 2.0' attempts would take their inspiration more from these evangelical movements rather than more 'established' religions and religious practices.
