My two cents: I'd change the design: I'd make the front page more like Google. (Search box in the middle)

And your site is full of features - like "Browse baby names..." and "We have amazing maps..." those thing are features - what you need to do is list the benefits. You should tell the users what value they get. Example: Our coats have double lining = feature: Our coats keep you warmer = value.

And from a users experience point of view: The site isn't very instructive and its hard to navigate.

For me I want to use the site to find the least "popular" name - I guess a user can figure it out by your maps and boxes - But wouldn't it be great to just type in a name and get a page back with a "name popularity" map? Or if I need suggestion for names maybe you could do that too via popularity - by entering a state?

Like I said just my two cents.
