Chuck, unfortunately lots of people don't know how to use the social media platform. For example, when I see a post that I like, I will save it, therefore if it gets buried, I don't care because it is saved in my list so that I can go back to it any time. People that are scared of their identity being stolen or having to see garbage are the ones asking for it to happen. I have two Facebook accounts, one with 20 friends for family ONLY, so that we know what's happening in the family, the other is ONLY train related NOTHING else, I have full control. For every group or page I join, I control the notification I want to see. If someone wants to follow my page, before accepting, I will check them out and I can always ban them later. If you don't want to follow a person, you can follow groups or specific pages dedicated to a persons layout or a special interest, such as weathering or operations, etc.
The way I see it, lots of old folks don't like changes, lots are set in their ways and lots are closed minded. They will only see the negative aspect of something new. I try to be open minded to everything new, but sometimes I will need lots of explanation to understand why I should accept the changes, but will never throw it out the window before trying it.
You don't need to migrate to the OTHER side, you can stay here and talk about the weather and how your day is going AND help people with their hobby or get answers to your questions, see wonderful layouts being achieved and all the new stuff people come up with on Facebook and Youtube.
To each their own, but those on social media will tell you, we definitely get more out of social media than forums, I know I do. Just look at Ken's, Dave's, even my layout thread or others and if there's more than 2 reply posts on an average, that's about it. I get 50+ per post I make on Facebook. I agree that if you've got nothing to share, that you don't want to help others or are not interested in what's new, than yes, no need for social media.
