Hackers worry me. Saw a programme on Australian TV a few nights ago where some patriotic Chinese hackers are working out how to disable the West. Programme said there were several hundred thousand of them in hacking clubs and supposedly they disabled the power supply in North East US a year or so ago.
Guess the olympic games were boring to watch so they made their own fun.

These days, most hackers aren't doing it for fun. They're doing it for profit.
