Strictly from a format point of view, it's junk for a car club and related activities/information.
I've not owned a 1/3g in the last ~4-5 years so I've not been very active but I'll never not be a pepper and I'd like to maintain the community for the long-lasting institution that's been built.
Facebook is disposable, superficial, and generally ill-suited for the retention and useful organization of specialized information pertaining to 1/3g's and the community that came up around it. I'm not getting into any of the political/polarizing social issues on the subject here, fb is just a shit format in general.
No, I'm not suggesting that everyone abandon the fb group; I'm just advocating for people to treat it as a supplement or a phoph gallery exchange rather than the main avenue for rpr content as it seems to be lately.
