Did you know there is a Potty Training topic on this board? And one specifically for parents of pre-teens as well as one for parents of actual teenagers? There's a topic for car seats and well ... the list is almost endless.
AIBU to think that the reason people post unnecessarily in AIBU is that there are too many topics with not enough traffic in them so they use AIBU to get replies as they know they'd go unnoticed if posted in the relevant topic?
