Yes! I couldn’t agree more! I like social networks as much as the next guy – their advantages are undeniable. And they’re fun, if they don’t become an obsession. What I have a problem with, is exactly what you pointed out: the obligation to share things. Musical taste, pictures, thoughts (I still loathe Twitter, although I get its importance in a marketing context). What if I don’t want to share? The difference between “being able to” and “having to” share is not that subtle. Whenever I talk to other people about it, though, I’m surprised to find out how few of them are actually bothered by this problem, or even share a thought.
