When a whisper isn't quiet enough to keep something secret

from here

You might be thinking that all these secrets that were exposed aren't linked to anyone's real name, so people's secrets are still 'secret', but people re-use usernames across multiple sites so it could be de-anonymized that way. Also the data includes locations, so you could look at entries from your area and factor in the other included details like age, gender, place of work, etc. to make educated guesses about whether they're someone you know. Add to that the fact that the secrets aren't just passwords, they're often stories with details that other people might be familiar with (at least in part).
