Hackerdom easily tolerates a much wider range of sexual and lifestyle
variation than the mainstream culture. It includes a relatively large
gay and bisexual contingent. Hackers are somewhat more likely to live
in polygynous or polyandrous relationships, practice open marriage, or
live in communes or group houses. In this, as in general appearance,
hackerdom semi-consciously maintains `counterculture' values.
