For one, I am not part of this group. I'm not one of you, and I don't really plan on being one either. I definitely sympathize with you all, because you do have a community here, and I see that. So I get that this change hurts you. But I worked way too hard to get where I am now as a contributor (and not as a user) on this site to have it all removed.
Which leads to the other reason, I have a massive mountain of maps. Now while I don't know how Zooper would do it behind the scenes (whether he can wipe everything at once, or do it one at a time). But if I am to guess each guide has to be removed individually, no way am I gonna spend weeks removing my stuff. And yeah, that's how long it would take too.
People still come to me saying they've used my maps to this day, so yeah people do come here.
Youtube is great for a visual representation. But it lacks a lot when compared to the helpfulness of written guides/maps. Plus, I'm betting a lot of those Youtube videos wouldn't exist without our help, not to sound arrogant/egotistical.
No we do not get revenue from ads. SBAllen wanted to do this during the CBS days, but after a few years of nothing, CBS decided against it because it be too much work. Believe me, that annoys me to no end.
