Well HOMER the thing now is if staff wants Omni to be friendly, but felt that the presence of negative voting caused things to be worse in overall, then since it involves trying to make the site having less drama, it's them who have the last say in the matter. Same for bans and such. In thar case, if a member is so much against the change and is not fine with how the admins who are losing money into running the site are managing things here, then they have to find a different website or start their own. And I think leaving Omni just because negative ratings are no longer possible without giving a chance to see if it's really gonna cause problems would be as absurd (IMO) as leaving because a member likes TI-BASIC.
Besides, we had no rating from 2004 to late 2009. While there was a bit more trolling, it was just dealt with more warnings and bans. (kinda like a permanent nDoom policy, although during the nDoom policy, criticising how the site is ran was ban-worthy)
