I deleted Facebook almost a decade ago. And I don't miss it at all. I got everyone I talk to regularly to switch to signal. It's helpful to have something that works across all devices and can send high quality pics and vids to groups of people on different types of devices.
Working on setting up matrix and hoping to make it easy enough for my close family and friends to switch over since I know I won't be taking away any features. Self hosting has been a fun thing to figure out. And I like not having any ties to any corp. for my messaging.
