Whenever I see a button that says "sign in with Facebook," I just close the tab immediately. Am I the only one who does this? What's wrong with just having me fill out a survey of my interests if that's what you want?

Facebook is the only account that I keep to myself and people who know me. My Twitter, LinkedIn, Quora, Github and all the other stuff I can't remember, all exist to connect me to people I've never met. I'd way rather use one of those than Facebook.

"But John Dryden said he's not the point. He wants people to focus on the issue he raised: Whether school officials considered that students could incriminate themselves with their answers to the survey that included questions about drug and alcohol use."

To me, that sounds like an unusually thoughtful social studies teacher. He is relating the general concepts that he is hired to teach his students to a real-world situation facing the students, and that sounds like good teaching to me. He ought to get a promotion or a raise, based only on this news about his public behavior in the classroom.

It is, of course, sometimes appropriate for schools to distribute surveys to minor students in their care on which there may be questions about student behavior that may be embarrassing or illegal. But the teacher, based on the report here, is just asking his students to think about their lessons and what those lessons mean, not trying to undermine the survey process.

"But Dryden doesn't want this seen as him vs. the administrators. He said he knows they were acting in what they thought was the best interests of the students.

"'These are good, professional, smart people on the other side who want to do what is right by kids,' he said.

"He would rather focus the discussion on the survey.

"'I have asked people (the supporters) to talk about the survey. I think I am a sideshow,' he said. 'This (the survey) was rushed and it wasn't vetted.'

"'I'm not a martyr,' he said. 'I'm trying to refocus people's attentions. Calm down.'"
