I hate to say it, but I disagree with both of you.
I think Steve covering the story comments is nice, but doesn't really add to the community. Healthy and active discussions happened before he started the weekly reviews. It was always cool when something from the forums made it in to the pod, but it wasn't needed. Actually, now it feels more like Steve has to include the weekly comments, rather than he wants to.
As for the episode warning I think it adds more than it takes away. Yes, I'm sure it does scare off some potential listeners: It's supposed to. The warning is there to let potential listeners know that some of the content might be upsetting even though not all of Pseudopod's stories are as terrifying as Counting From Ten (few could be). Horror means different things to everyone, and as such even if there were gradated warnings they couldn't possibly be accurate for more than a handful of people. If the warnings were subjective (like Steve does) they would probably give away the scary part of the story, or at least spoil the tension.
I feel that the general warning and grab-bag nature of the stories is what I like best about Pseudopod.
If you know a zombie is in the basement, you wouldn't go unarmed (if at all), and you'd be a little less scared. Likewise if you knew what was coming up on Pseudopod you could brace yourself for it, and to do so, even to the littlest degree, would be cheating yourself out of a scare. And you came here to be scared, right?
As for the forums, I think there just isn't as much depth for discussion here as in the SF grounds.
Horror is such a subjective thing that unless we all want to get in to our own mottled psyches and childhood traumas I don't know how much there is we can talk about other than "yep, scary," "nope, lame," or "Would have been better if..."
