Try to help @manton and @macgenie with Micro.blog support. They will likely need it. If you see someone asking a question and you know that answer, simply reply. (This would be easier with search. When Mastodon blew up this also happened.)
Angelina Simms published her experience at WordCamp US this year. Note this bit about the Philly Burbs WordPress group:
Too often, we are surrounded by people who act like they are concerned about your well-being out of self-interest and totally disappear if you don’t fit into their grand scheme of things. That is definitely not the case when it comes to hanging with WordPress people, especially within the burbsWP community.
