Not a bad idea. I often don't want to go and read someone's blog, and if I do I know where I want to go to. What I come here for are the discussions. I have also wondered today whether the non-arts forums are a good thing or not.
I frequently get tempted into the science and technology forum because it's there and issues which strongly interest me come up there. But it's not what I'm here for really. There are plenty of other places where I can discuss science (and have more useful discussions quite frankly: While there are some scientists here - or science-minded people - we're a minority, and most of the posts, in my experience, are just like my contributions: here's an interesting bit of news). We're not about discussing science really, but arts and faith. I've contributed to other non-arts forums too when I arrive and something catches my attention - but I always feel that I've allowed myself to get distracted and I end up contributing a little less to the arts threads. Would it help to restore an allegedly lost focus if the only forums really were arts and faith only?
My general reflections on A&F: I've been posting here since last summer, having lurked previously. Many discussions have been tremendously helpful - including some about second-rate films. But a few have been wrecked by really ill-natured arguments. I would spend more time here if all the discussions could stay on track and they didn't get into personal attacks.
