You can always just keep them but not log in/use them. I do think there's a place for social media, as I have a lot of family added who live overseas and it is nice to be able to have a look at what they've been up to. But I do agree that a lot of people - myself included - spend far too much time on social media. I don't think it does us any good, either, to be honest. It just sort of makes out that everyone is happier, richer, and prettier than us.. way to damage self esteem!
