Many local groups use Facebook to organize/communicate though.

Via private groups: our local Atari group does and we similarly have one for regional vintage computer gatherings, my Church does, one of my Lodges does, one of my gyms does and I know of several others in the area that do.

Via pages/events: some local tattoo shops that regularly have events, several local venues, numerous gyms and their various strength competitions will have all communication/announcements through an event page associated with the page of the gym hosting the event, etc.

It's effective because people know to go check Facebook for an update about the group/event, you don't have to worry about an email ending up in a spam filter or someone not seeing a flyer posted, you can post real-time updates like when our meeting place for the local Atari group was closed due to the weather instead of needing to text 2 dozen people, or when snow/ice necessitates a Church event being cancelled or when there are storms in the area and we can post what members need help.

Then cut facebook usage as a tool too. #radical
