SF Signal is the clear winner here. Frequently updated, and always interesting – if you only have time for one SF website, bookmark Angry Robot’s (commercial over) – if you have time for two, SFSignal.com should be your site of choice.
Thanks, Lee! Your check is in the mail.
I’ll also take this time to note that the awesome Bibliophile Stalker, the blog of SF Signal’s equally-awesome contributor Charles A. Tan, has been named as Grasping for the Wind’s Best Fan Blog of the Year! Congratulations, Charles!
