You've probably read about it already - The Samaritans, a great mental health charity who offer a 24 hour helpline, have launched a suicide prevention app called Radar.You can use Radar to monitor the people you follow on Twitter to identify whether or not they might be suicidal. It scans through their tweets and flags any that use key words which suggest they might be feeling that way - e.g. 'hate myself', 'help me', 'depressed'.
In theory, the idea is that you receive an email when someone you follow tweets any of the 'key words' and you are then encouraged to follow up with it, either by Direct Message or offline.
In reality, this app presents a lot of problems and borders on actually being dangerous.
