" In recent months, Secret became a haven for bullies who, protected behind a veil of anonymity, viciously hurt fellow teens in school. "

" the secret is constrained to friends or friends of friends, it isn`t very difficult to figure out who`s saying what, especially if you have a small social circle. If you exposed your infatuation for a boy at school, it`s very likely that a close bud would figure out it`s you who said it. That might not be so bad if it`s something as innocent as that, but for something much more salacious? It might be a little TMI. Secret did change its design so that you could share your confessions on a global location-based list instead, but that made it a little too similar to other anonymous-sharing apps like Whisper and Yik Yak.
