Forums are dead, Facebook finally killed them because it is much more useful, most people already have accounts and with Groups and Pages make it a lot easier to organize and talk about a whole host of different things.

Forums don't tell you anything except what the few weirdos who still post on Forums think. Seriously, this forum has what, 20 regular posters? So only a few play Age of Sigmar, only a few played Fantasy and most of the talk then was on lists building, which isn't a factor any more.

Otherwise, I guess Frostgrave has been a massive failure then, because the one post made about that game that I can see didn't get a single reply (However, when the post was turned into an article on blog, generated a ton of shares and likes on Facebook a few comments and lots of views.)

Canary in a coal mine? Maybe, because its mostly empty now and there is just a single person chirping on, ignored by everyone on the surface.
