Group chats are basically the Circles that Google+ saw the need for but could never get fully set up. A lot of people don’t want to share personal updates and photos to a broad swath of friends and acquaintances.
Meanwhile Instagram and Facebook keep evolving. Facebook is turning into a weird Reddit for older people. Instagram is turning into a hipper LinkedIn, where artists, musicians, and local businesses share career and business updates and advertise their wares.
No LinkedIn, not you, you boring Ted Talk humblebrag.
If you crack and admit it’s fake, everything falls apart and it’s your fault. Expulsion out onto the street follows.
Even worse, now everyone else is going ‘how could you be so dumb to believe it’ and/or ‘you sure fucked up by admitting it was fake’ all at the same time.
Not necessarily mutually exclusive. It's like professional wrestling, stage magic, or politics. Some lies people really love.
