Well, that makes her perfect for 'twit'ter, doesn't it? Personally, I signed up last Spring. I visited a few times, and haven't been back since. I agree, it's absolutely worthless, mostly populated by people who mistakenly believe they have something to say, yet can't even state their swill coherently.
Facebook is the same, IMO. I signed up there also and haven't been to it in months. The only redeeming value it provides is a way to keep in touch with friends and relatives, yet many use it for mundane, trivial chat. No one knows how to communicate any more.
Good ol' FReepers, love the comments about this silliness. In our 60s, my wife and I have been trying to encourage grandchildren, who are so "into" this junk to email us occasionally to stay in touch over long distances, to send photos (like we do), short video clips, etc., to enjoy getting to know each other better.
I have a gift of cartooning so I cartoon on each of their Christmas, birthday, other occasion cards (there's seven grandchildren, it can be pretty busy!). My cartoons are family oriented, familiar things to relate to so we still use snailmail too!
But no, too lazy to even do that yet they whine to their parents "if we only had [insert latest technology here] we could STAY IN TOUCH". Yeah, right.
