Substratum? Never heard of it but I'm glad you've brought it to my attention! Thank you friend as I'll be checkin' this one out as well. As for ISP's controlling access to information for profit well what else is new on this mud ball we live on. Everything is for the green bottom line right? Shame really. I suppose when the masses find a way off the rat wheel/owners monopoly board we'll see some real change for the better. We've got a long journey ahead but we're makin' head way in my eye's. The way I see it is Gooberment interests are owned by corporations and that is dangerous.................
