Hmm... although I've never been to any of these rituals, but from reading the descriptions, it hasn't been my impression that it would exist only for community-building. For example, I found the description of the 2011 ritual touching on an emotional level even though I was reading it all alone at home, and I expect that the rituals would also have given me a strong emotional kick that wasn't directly related to the group bonding aspect. Going out to a movie with friends would probably be a good analogy: being in a group does enhance the experience, and the group bonding is a plus, but the main reason we go there is the movie itself.

The social bonding and getting to meet new folks was not what gave me a strong feeling of "man, I want to participate in that" when I read the description of the original ritual. In fact, all of the social bonding stuff was just extra: a nice plus, but hardly the point. What attracted me was, well, the ritual itself: the feeling that it could give me a deep, lasting emotional experience that'd move me to the core, a faint echo of which I felt while reading the post. That would ultimately be a solitary and personal experience, even if I needed the presence of a group to help me achieve it.
