I found this a while back, on a peak-oil forum actually. It's an armageddonsite run by non-religious people, and it has an active board too. The Watchtower is only briefly mentioned in the failed predictions section. The site examines in a rational way the threats that exist in three sections: casualties by man, casualties by nature and cosmic abberations. Also it deals with some popular conspiracy theories, but they are really down to earth on it. It's like popular science in a "discovery-channel" kind of way, i hope you like it
