I reluctantly use Facebook still as it’s still the best platform for trying to organise things and keep in touch with riders, but I’d very quickly jump ship if this changed.
I’ve never used Facebook login though.
I do honestly wonder whether some of this is tied into The unicycling organisations desperately need your help!. Back when Facebook was newer, less horrible, and practically everyone used it, it seemed much easier to stay in contact with people and keep them updated with goings on.
Now there’s no one platform that everyone’s on, and I don’t think that helps with enabling people to stay in touch!
