Both from a personality standpoint of "individualism" and from a more general logical thinking/epistemological standpoint ("A is A") it seems to me that Objectivist values and beliefs are Hacker values and beliefs, or, at least, a "hacker" is statistically more likely than the average person to gravitate towards objectivism.
