The following piece from NBC's Helen A.S.Popkin is a great article on Ask.fm and the recent media storm around it.
Popular with kids, and — until recently — obscure to many adults, Ask.fm is a Latvia-based social networking site where members interact by inviting others to ask anonymous questions.
Though the site has more than 65 million members who interact in more than 30 languages, it wasn’t until Monday that Ask.fm made headlines in the United States. That’s when kidnapping victim Hannah Anderson, barely 48 hours after her rescue, logged on using the name “Hannahbanana722." Her identity later confirmed by her grandparents, Anderson openly answered personal questions about her ordeal, posted by anonymous strangers. She also posted several smiling selfies — cellphone self-portraits — as well.
