I feel that it is a bit unfair that rep doesn't carry over between the parent site and its meta. This is the case for every single one of the sites I've been a part in on the Stack Exchange Network. It makes little sense for someone with 5k+ rep to come to its site's meta and have just 1 rep. I know that at least some sites have rep being shared the other way around (meta->parent), but the fact that 0 rep whatsoever is shared from parent to meta seems somewhat illogical to me.
