Can you surf the Web and chew gum at the same time? Perhaps, but you'll be wasting your time. That's according to Dentyne, which has a bunch of posters up in the NYC subway (and probably elsewhere) encouraging young people to get off their stupid computers for five minutes and "Make face time." Dentyne can help in this regard by giving you decent-smelling breath—something that's all but unnecessary on social networks but handy in actual social encounters. The ads, which seem to have originated in Canada, may run the risk of making Dentyne sound parental. But it's nice to see a youth-targeted campaign that has nothing but contempt for Facebook.
