I have never had a Twitter account, nor have I ever posted to Facebook (although I do have a page, so the press have a nice picture of me in case I'm kidnapped or something, as well as 50 or so "friends", although I have no idea who many of them are or where they came from). So I don't quite get what this guy is complaining about. How was posting to a privately owned (by someone else) but publicly broadcasted platform, designed to attract freely contributed content in order to build an advertising channel, ever supposed to be "intimate"?
You should have a Twitter account. I have a Twitter account under my real name with a keyboard smash password, just to ensure no one else can take it. Same with Facebook.
Having name providence provides some amount of deniability though. If there's multiple accounts with the same or similar then it takes deliberate effort to create mistaken identity.
