Coming back to the topic of the node:

There probably are more bisexuals these days. There are probably more homosexuals too. There is a ludicrously easy reason for this:

People are more tolerant

OK, there's still the KKK, queerbashers, the upright and true standing citizens who can't accept that there are some people who love their own gender. But if you told most people, their reaction would not be to stone you, but probably merely to look at you in a wierd light, wondering why the hell you told them.

Whilst the Kinsey report was flawed, his suggestion that sexuality is a sliding scale rather than just three-states has merit. He suggested that 0 be entirely homosexual, and 10 be entirely hetero, with the average probably being somewhere near 8.

OS: opposite sex, SS: same sex.

0: 100% Homosexual
1: Strongly homosexual
2: Has looked at the OS and thought him/her attractive
3: Would consider having sex with the OS, but would much prefer the SS.
4: Has a preference for the SS.
5: Totally ambivalent - 100% bisexual.
6: Has a preference for the OS.
7: Would consider having sex with the SS, but would much prefer the OS.
8: Has looked at the SS and thought her/him attractive
9: Strongly heterosexual
10: 100% Heterosexual.
I'd probably define bisexual as between 4 and 6... before this century, being anywhere below 9 in public would probably make you a social pariah.
