IIRC Orson Scott Card had his own area on AOL in the mid 90s, and possibly earlier. Not sure when he moved to the big-boy Internet but the name is the same, "Hatrack River".
It wasn't a 'blog' per se, more of a forum, I think ... I only dropped in once or twice and my recollection was that the discussion was (at the time) more about his religion than about his writing.
But if he'd just wanted to speak to fans he's certainly had an outlet to do so for a long time, and had it at the time the review was written. Presumably he chose to write the response in the form of an Amazon review consciously, and not for want of some other venue.
