Of the 22% that do use Twitter:

85 percent follow friends 54 percent follow celebrities 29 percent follow family 29 percent follow companies

Not much for brands to cheer about, but keep your chin-up, you have the same attention as Gen Y’s parents.
What do you think? I would have thought that more than 22% would be on Twitter, you? Get the full study details from PMN.
