Be the change. People are lazy in general and will use whatever is easy and others use not giving too much thought to consequences.
In my circles I always openly say "I'd love to, but I don't use Facebook" - so if someone wants to have me included, they need to think about a more democratic way to include others. It's not egoistic - many other people don't use FB either. Excluding them just because a group of people is too blind to notice is a very negative approach.
This is the problem, I'd be literally the only one. I tried it once - of course they didn't exclude me, but a lot of info got to me too late (when I had other plans already) and smaller events not at all.
The way I see it is: if friends won’t stay in contact with me without me being on Facebook... then they are not really friends. Leaving FB actually improved my social life because it became clear who were the real friends.
They do stay in contact! This is about small-ish events like a friend posting "hey guys, I'm hosting a dinner tomorrow". I can't blame them for forgetting about me (our group is rather large), some of them don't even have my phone number.
