This would be much more applicable if there'd be a culture distinguishing the two kinds here at HN. Most submissions about Anonymous or "cyberwar" call them hackers, i.e. there's no "hackers vs. crackers" mentality. (Never mind that for me, having grown up in the 80s, a "cracker" is someone who circumvents the copy protection of a game)
Still, considering that the term has morphed once again into something greater ("life hackers" etc.), I don't see a real danger in the name of this site. Never mind that we've got way more capitalistic neo-yuppies here than phreaking aging hippies…
