Earlier this year I noticed a mention of the Flat Earth revival in the pages of the alternative magazine Fortean Times. That was in the September 2015 edition and it briefly noted the recent "flurry of activity on Flat Earth websites" and referenced Eric Dubay's Atlantean Conspiracy website.
The mention came in the Conspirasphere section of the magazine. For context Fortean Times is a magazine that likes to have its cake and eat it when it comes to conspiracies. Discussing them within its pages, but doing so with a healthy dose of mainstream scepticism and humour. I can't really complain about this too much, as I sometimes do it myself on these pages.
Deep down I'm hoping that at some point they'll do a full cover story about Flat Earth, but I think that may be a long time coming. Even if Flat Earth has aroused their curiosity, I think it still seems to be a little taboo - even for those writing from an observer, rather than a believer, perspective. I'll keep a lookout though.
I remember playing the same game with Fortean Times regarding 9/11. Wondering when they would finally start mentioning the mountains of alternative material out there about it. At first it started appearing in the magazine, but with a "how can people believe this stuff?" sense of derision. Then gradually that started morphing into a more tacit acceptance that maybe the conspiracy theorists have it right about some things.
In fact, in last months edition (November 2015) they discuss, again in the Conspirasphere section of the magazine, how the conspiracy industry has grown so big that it's started to develop a mainstream and an alternative of its own. And also how it's started to develop a "tabloid/broadsheet" divide, with sensationalist conspiracy theorists like Alex Jones on the one side and more "academic" theorists on the other. It's almost like the writers of Fortean Times are trying to justify their own obvious interest in the subject ;) ..hoping that they can somehow exist on the more respectable side of the divide without acquiring all the negative connotations of the "conspiracy theorist" label.
If any Fortean Times writers are reading this, unlikely though that is, I would say don't worry too much :) ..conspiracy theories are definitely mainstream now. A historic fashion shift has occurred and we can't go back. The only people who look like "loonies" these days are the few people who can sit through, say, September Clues and still believe they can trust their governments and media. The magic bean buying segment of the population XD
