Maybe because it's mainly djent and less classic metal/rock interest on the board nowadays too?
I don't think that if you took a poll of every visitor to the site that this would pan out - especially if you polled those who just drop in and read and don't post or even those who read regularly without even being a member.
I think you will find that there is a healthy mix of tastes ranging from rock , pop ,blues, metal, RnB, surf, country, reggae, soul, gospel, jazz, punk etc etc (sorry if I overlooked your genre)
I do think that maybe there is a lot of vociferous posting from a minority who share certain more "contemporary" forms of extreme metal/djent /black metal etc, and it is possible to feel that the forum has swayed a bit far that way at times.
Maybe these are just the music forms that appeal to those with time on their hands to post a lot.
It
would be nice to see a bit more variety at times and I'd enjoy hearing views on a lot of the other genres and which pickups are great for them. I'm sure it would be good for a lot of the other less vocal visitors too.
