I've taken courses on terrorism and have read and struggled with many definitions of the term myself. But personally, I think it is taking it a bit far to consider web-based hacking as discussed here "terrorism."
In general, I agree with much of Star Puffs' official U.S. definition (politically motivated, targeting civilians, violent behavior). Except that I might not include actions committed by "subnational groups or clandestine agents." Though it may be abhorrent, I don't consider acts by a legitimate or semi-legitimate governmental entity terrorism, and that definition allows for it. And frankly, some behaviors engaged by the U.S. and other governments would be lumped into the category of terrorist behavior by that definition.
I might also throw in a bit about motivations and the theatrical nature of the act, but that makes it harder to quantify which is probably why it isn't in such a "technical" definition. In a way, the "political" component subsumes those others anyway.
