I live in the mid-west, where these organizations were very common. I'm ~50 years old, and I don't know ANYONE who's in one of them, and every one of them around the area that I drive by is in disrepair. I expect them to disappear with the boomer generation.
Another feature of my location are all the small "mainline" churches (Presbyterian, Methodist, et. al.), who hover around 30-50 people, and have no members younger than 60. There's a business opportunity coming to buy up a lot of prime real estate when these churches fold in another 10 years.
I think a huge problem with finding "community" now is the utter isolation caused by social media and access to the thinnest slice of the news you want to tolerate. It has created a culture where people are only tolerant to their SPECIFIC view of the world, and it's just really hard to find people who think EXACTLY like you.
I actually tried to join a couple of those sorts of organizations, and I found them all very off-putting. Between the weird elitism, the arbitrary and time consuming hurdles for membership and the feeling that everybody there felt 20+ years older than me (even when they probably weren't) didn't make it seem like a good time.
I like the concept though, I just wish there was one that felt more up to date and actually felt like a sort of thing I'd want to join.
I think just talking to an Apple dad about his life and priorities would be extremely eye-opening for a lot of people on HN.
For the tech and maker types, a hackerspace/makerspace might be more appropriate.
If something exists but people aren't using it, it isn't the right solution. It might be hard to say why it isn't, it could even just be a marketing problem, but nevertheless the problem isn't solved by its existence.
