I’ve been looking forward to this experiment. A group of authors are writing and posting reviews at Writers are Readers.com. So far, the reviews are nicely done and by an interesting group. But they have only one SF writer I recognize, so… if you’re an author who likes to read, you might consider talking to these folks.
And there’s a review of Poltergeist done by Jayne Ann Krentz there. You’ll have to ferret it out for yourself though. There are gems to be found if you dig around.
