I've thought a lot about deleting Facebook lately. As it is, though, I only check in once or twice a week, and I've never used Messenger. 

It does keep me in touch with a couple groups and friends I wouldn't hear from otherwise. And if I hadn't checked in four months ago, I wouldn't have known about the job I have now, which is essentially the only job I ever actually wanted. So I feel like deleting it entirely would be setting me up to miss opportunities.

So I think it's a tool - and one that needs to be used in moderation. But when it feels like you're being used by a tool rather than using it, yeah, it's probably time to get rid of it.
