Yeah, absolutely. I use Twitter far more often than Facebook these days, and I very rarely go online to check what’s going on. It’s handy for keeping in touch with certain people, but most of my friends on there are old school friends who I’ll probably never talk to again.
Could I go a month without Twitter? That’s a whole other issue. Maybe, but it’d probably be the end of me using Twitter, as I’d just get so behind and uninterested with it.
