There really aren't enough social networking sites, so let's add another one.
It's called Ask.fm and it's all the rage among the kids these days. Unfortunately, it's also become a popular site for cyberbullies. So much so that companies have started to pull their ads.
The site is similar to the now-defunct Formspring question-and-answer site. Half of the site's 57 million unique users are under the age of 18.
