You are aware that that comment in the blog article (not mine) was tongue in cheek, right? I mean yes, I want to know what other people are reading, but it is not the most important problem in the world.
Also, I think it is weird if you are not at least a little bit curious about the people around you.
This is another one of those online conversations that there are all sorts of people who are very different from each other. I don't think we are even speaking the same language.
All I was saying in my first point wass that its weird that people want to show off what they are reading.
My later point is that it there is a fine line between healthy social curiosity and straight up creepiness. If you would not be comfortable asking the person your question its probably creepy.
