I'm a big sci-fi and fantasy fan.
But with a taste. Don't try to make me buy any of the fandom stuff, but you'll find for sure in me a good public for intelligent (at least, I hope it sounds intelligent for others too) discussion on the genres.
On that vein, I found two funny and intelligent articles by Michael Moorcock discussing some issues on both genres.
I don't share all the points he made, but he sure made some good ones.
These are the links:
Also, there is online a seemly interesting and huge essay on Ursula K. Le Guin's works:
Coyote's Song: The Teaching Stories of Ursula K. Le Guin by Richard D. Erlich.
I'm slowly reading through it. I have no opinion on it yet, other than it seems to cover everything Le Guin wrote.
