I've been happily writing for The Tyee for several years. It's a lively online magazine with a focus on British Columbia but with plenty of attention to the rest of the world. The Tyee is now trying a little viral marketing to attract more readers: Tyee: Join Us! I'd be interested to hear your reactions to this approach.
The Tyee has also published a survey of Independent Media: Vibrant and Growing.
By the way, I've just published a piece on avian flu in The Tyee.
I'd love to hear about other good online magazines, especially in Europe, Asia, and Latin America—in any language.
