Its something to reflect on, that those small nonmainstream groups, communities, cultures that you might be a part of everyday are mostly completely empherial. Records of what people did and said are bound to be lost, noone is going to curate or summerise the history. I faced this when yahoo groups was deleted. I found many messgae boards of a the transient 'teaching abroad in japan' local communities from ten or more years earlier, before facebook. it was so strange to think all these people had the same conversations and questions and experiences, but there was no connection between that community at that moment and the one when I was part of it. I suppose the history in the facebook pages will be even more easily lost, and then the discord groups or whatever they're using these days will be lost even after a single year..
