You put the name and they tell you how many people with that name were born in each year. There was this crazy graph that moved when you moved your cursor. And it showed the trends, like when the name would peak in popularity.
I thought it was babyname wizard, but that site is totally different. And it keeps "not responding" on me, so I wouldn't advise going there.
Re: What was that baby naming site from a few yrs back?
