Web site Minti lets you share, rank, comment on, and search parenting advice.
“We started with the goal of supporting parents worldwide to become better at caring for their children. Where does the best advice come from? The vast majority of parents told us “from other parents”. Minti provides an online community for parents to both share and rank advice about parenthood in an easy and fun environment.”
The site is fairly young and you might find it lacking in some information that you as an experienced parent might find valuable. I like it as a means to gauge other peoples opinions on the various trials of parenting.
