A simulated and one-sided relationship with a public figure; a similation of intimacy from the part of the performer that is often used to wring profit and attention from the smitten audience, who begins to falsely perceive the performer as a friend - or lover.
"The more the performer seems to adjust his performance to the supposed response of the audience, the more the audience tends to make the response anticipated. This simulacrum of conversational give and take may be called para-social interaction."
"Para-social relations may be governed by little or no sense of obligation, effort, or responsibility on the part of the spectator. He is free to withdraw at any moment. If he remains involved, these para-social relations provide a framework within which much may be added by fantasy."

Online, the line is blurred; social media makes the sharing of mundane events normal. There's a sense as if these strangers are letting you into their lives - and on some level, they are. It's an interesting thing to witness when the private/public 'line' becomes invisible: stalking, harassment and obsession are facilitated by this oversharing.
But to the Webmaster, parasocial relationships have an added relevance. As a fan of many bands, it is true that the lack of knowledge about the personal lives of the performers makes them more attractive and interesting. There's nothing interesting about knowing about someone's pets, family, girlfriend etc. to the Webmaster.
Stars being 'just like us' is boring - why would I want my favourite singers to be normal people? I don't want to be friends with them, their private lives have nothing to do with me. I don't want to feel close to a stranger, there's enough socialisation in real life to keep me going. It's pathetic to hinge your wellbeing on the fate and behaviours of a stranger that doesn't know you exist...
