Er. Hate to tell you but I think the reason you think people on blockland hate it is because a lot of people everywhere hate it... .-.; (I bet they even have people on gaia who don't like it)
I, personally, haven't noticed anyone singling out gaia as something they hate and/or wish would go burn in hell.
EDIT: Well. Then again. I haven't been here for long so I guess I can't be talking about the forums way back in the day.
