BiMagazine
http://www.bimagazine.org/
An online bisexual magazine with a lot of interesting articles and a very international focus, with a number of articles on the status of bisexuals in different parts of the world. Also includes poetry, visual arts and music coverage, though some of these sections still seem to be pretty sparse. The majority of the content is under non-fiction.
Bisexual Resource Center
http://www.biresource.org/
Web site of an international non-profit organization dedicating to educating people about bisexual issues. The main page of the site is a news listing, in a blog format, but there's also a very extensive resource directory with hundreds of bi-related links.
Bisexual.com
http://www.bisexual.com
Probably the biggest online community for bisexuals, with articles, discussion forums, personal ads, live chat, and more. Rather annoyingly, you have to register in order to access most of the content, and the registration process seems to assume that you're looking to place personal ads, requiring you to indicate whether you're a single or couple, for example. No way of indicating if you're in something like a poly triad, either. However, it's otherwise a good site.
Bisexual.org
http://www.bisexual.org
Though apparently run by a nonprofit, this site has a very commercial feel - it seems to be primarily a dating site, with connections to a couple of porn sites. But it does also have a (very small) articles section (very small as in only two articles, when I last checked), plus discussion forums and a reasonably decent resources section. They also put out BiMagazine, which I've listed separately as it's a separate site with a very different feel.
Toronto Bisexual Network
http://www.torontobinet.org/
This is Toronto's main bi organization, though it also includes two gender-specific subgroups, Bisexual Women of Toronto (BIWOT) and Bisexual Men of Toronto (BIMOT), listed separately. The TBN site includes a local events calendar, a timeline of bi community development in Toronto, a listing of bi resources (books and web sites), and more.
