I deactivated my Facebook account several months ago, and it's been about 90% great, 10% frustrating. It's great for all the obvious reasons (less timesuck, less compulsion to endlessly scroll your life away, no notification interruptions). The frustrations are real, though. Primarily it's around events and photos. There are some communities I participate in that regularly organize events through Facebook, and now I…
Can't you just have Facebook and only use it for the events/photos? I've got a Facebook but never use it for posting/looking at other people's posts. Every now and then I'll get an invitation to an event which is really all I use it for.
There's a few communities that I'm in that I wouldn't even know about, event-wise, if I wasn't on Facebook. I can't imagine missing those- I'm surprised others don't use Facebook more for events.
As others have mentioned, I also use News Feed Eradicator, so I don't even see anything on Facebook, unless it's one of my close friends. It's fantastic, and my time on the site is probably less than 2 minutes/day.
