To add to the parent comment, make a list of people you'd like to stay connected with and add an event to your calendar a few times a week (I do two). Those events are to reach out to one of those people on the list and catch up with them. You can't follow a thousand people like you can one Facebook, but the conversations will be richer and 1000 close connections with distant people probably doesn't provide deep connections anyway. This has been good for me.

Another one I heard in Digital Minimalism by Cal Newport is to hold "office hours" in which you're available for conversation with anyone. What's nice about these is that you can schedule them during downtime like a commute or a regular walk, so you're not losing any extra time.

Might come off as robotic, but scheduling regular conversations with those who are closest to you is really nice and makes sure you're always in communication.
