Just watched a documentary about Foxconn which tries to filter out suicidal employees. Sure Facebook's profiling would be useful for many companies who put a high pressure, and their HR depts. Not sure humanity is progressing, though.
The cynic in me says they don't particularly care about the high suicide rate of assembly line factory workers in China, as long as said factory workers don't off themselves while on company property or at the company dormitory. Because that's bad PR, guys.
