Uuuuugh, why does that proclamation get my hackles up?

I'm FB friends with a writer for the Philadelphia Inquirer, and he writes mostly features, lifestyle stuff, that sort of thing. He sometimes posts on FB asking if anyone has experienced __________ and if they'd like to talk to him about it for a story. Tonight he posted asking if anyone texts/tweets/emails etc while watching particular shows. A bunch of people (including yours truly!) replied in the affirmative and then someone comes along, OF COURSE, to say "I don't watch tv. And I don't tweet or text. That should skew your results summat!"
