You can easily replace FB with Instagram in this context. Nobody I know personally posts very much on Facebook, but they do post their updates on Instagram stories.

Facebook's last hook on me is groups - small town community groups especially. If you live in an area with its own group, there's a high likelihood that it's going to be on Facebook.

I don't really have the time to campaign to non tech-savvy retiring gen Xers and their parents that I don't want to use Facebook to know what's happening in my area, find services, etc.
